Mango pudding for adults

Every decent dim sum teahouse tends to offer little bowls of mango pudding on the dessert menu, but I almost never order it. The problem is, the pale orange stuff generally referred to as “mango pudding” nowadays rarely turns out to be a celebration of one of Mother Nature’s all-time greatest hits. 

I mean, when made correctly this is little more than an inspired combination of dead-ripe mangoes and fresh light cream. So, what you should be reveling in at the end of a dim sum meal or Cantonese banquet should be nothing less than divine, and when you look at the ingredients you'll realize that by all rights mango pudding ought to be awfully hard to mess up. 

Part of the problem is that most restaurants expect to serve this to the kids or to people who just want something on the order of ice cream for dessert. And so, the mango pudding we all get served will be cold, it will be sweet, and it will most likely be made from some mix with canned mangoes added and maybe a maraschino cherry on top, if the place really is trying hard. But that doesn't come near to the required simple perfection of this dish, which will transport devotees like me into a state of shivering ecstasy.

No, for that I have to make a batch of mango pudding by myself. And I’m here to tell you how. And the good news is that it’s not at all that difficult a task, especially when you consider how much gratification is at stake, how short life is, and how few perfectly ripe mangoes we manage to enjoy in various iterations before we shuffle off this mortal coil.

A great mango pudding should be a cool and fragrant bath for the senses. When made correctly, this luscious dessert offers a delicious cosseting for the tongue in between pillowy cubes of fresh, fragrant mangoes.

This is, in short, heaven in a bowl.
A wrinkly ripe Ataulfo (aka Manila) mango

Like just about every other great dessert that I love, mango pudding was not designed with the kiddies in mind. Rather, this can and should be a dish of great sophistication, full of flavor, not too sweet, capable of surprise, and immensely satisfying, especially after a long and filling dinner.

The one really important thing you have to do if you want success is get ahold of some very tasty, perfectly ripe, and not at all fibrous mangoes.

Right now is a good time in the Bay Area for Ataulfo or Manila mangoes, which are very aromatic, creamy, and relatively small. But any good mango will do. Learn to discern the varieties that you like (my other go-to mangoes are Kent and Haden, but that’s not at all a complete list) and keep an eye out for them, because this dessert requires careful planning.

What you have to remember is that you almost never can get perfectly ripe mangoes in the market, as they bruise and squish so easily. Instead, hunt down delicious specimens that show great promise (I tend to lug home a whole case of the fruit in greedy anticipation of meals to come) and let them ripen away in the kitchen. When they start to smell fabulous and the skins are a bit wrinkled, give the stem end the very gentlest of squeezes to confirm that the mangoes are ready to be celebrated in style.

Mango pudding was probably descended from India’s mango phirni and was possibly introduced to Guangzhou (Canton) by the British, who had lots of fingers in a whole lot of colonial pies. Nevertheless, this has managed to become inarguably Chinese over the past hundred-plus years.

And yet, in spite of this illustrious history, I really couldn’t leave well enough alone, now, could I?

Diced mangoes
So, you get your half-and-half here instead of condensed or evaporated milk. You have a touch of sweetener instead of lots of sugar. You have way more mango in there than probably is legal in many states. And… I’ve slipped in some rum. You of course don’t need to include it if you’re serving this to children or other teetotalers. But it’s great with this little extra dash of fun.

By the way, this is a fantastic dessert to serve after a fancy dinner at home because it can be made well ahead of time. All you need to do is add the garnishes and serve.

Mango pudding chez Huang
Huángjiā māngguŏ bùdīng 黃家芒果布丁
Guangdong cuisine
Serves 4

Pudding:
1 packet | 6 g unflavored gelatin
¼ cup | 60 ml cool water
Around 1½ pounds | 750 g ripe mangoes, which would be about 3 Manilas or Ataulfos (see headnote)
1 cup | 240 ml half-and-half
¼ cup | 60 ml mango rum, passion fruit rum, or dark rum, or you may add agave syrup or sugar to taste

To serve:
¼ cup | 60 ml half-and-half
Mint sprigs

Easy but delicious
1. In a medium work bowl, sprinkle the gelatin over the cool water and let it soften while you prepare the rest of the ingredients.

2. Peel and pit the mangoes. Puree enough of the mangoes in a blender or food processor to give you approximately 1½ cups | 360 ml. Cut the rest of the mangoes into small (½ inch | 1 cm) cubes.

3. Pour the half-and-half into a 1 quart | 1 liter heatproof measuring cup. Microwave the half-and-half for a minute, stir, and then microwave again in short bursts until the liquid is very hot but not boiling over. Stir the softened gelatin into the hot liquid and swish things around gently with a small whisk until the gelatin is dissolved. Then, stir in the mango puree and either the rum or the agave syrup.

4. Divide the pudding among 4 (1 cup | 240 ml) dessert bowls and chill for about an hour, by which time the pudding will have thickened a bit. Reserve a couple tablespoons of the cubed mango for garnish, if you wish, and then divide the rest among the bowls, stir very gently to mix in the fruit, and refrigerate the pudding for at least 2 more hours and up to 3 days. Serve chilled with a small puddle of half-and-half on top, as well as a couple of mango cubes and a small mint sprig stuck into the edge to snazz things up.

Rev up for Chinese New Year!

The Year of the Pig is almost upon us. February 5th is the first day of the lunar new year, which means it's time to get some holiday food ready. 

Radish cakes are always at the top of my list. 

The English name is, admittedly, lousy. Chinese radishes are nothing like our little red jobs... this vegetable is big and juicy and white. 

Some people call them turnips, but don't let them fool you. These taste like radishes, but without the heat. 

Crispy exterior, creamy insides
Chinese and Korean radishes (luóbō) are best here, but daikon will do in a pinch. The main thing is that the tubers are fresh and sweet and heavy. Asian radishes are at their best in cold weather, so now is the time to buy them.

Be forewarned: radish cakes don't look or taste like cakes. Luóbō gāo is a savory steamed pudding, if I'm going to get all persnickety on you, and the interiors of these slabs turn fabulously creamy when the exterior is fried to a crisp. 

Most restaurants serve this as semi-cold slabs that have been sautéed on two sides. However, radish cakes  can be oh so much more delicious, for the perfect luóbō gāo is served as crunchy slices or nuggets. A nicely browned crust on every side serves to (barely) control the chaos inside: a molten rice lava spangled with bits of Chinese cured meats and mushrooms.
Juicy Korean radishes

A gentle taste of radishes hover in the background, with gravelly bits of sausage and mushroom spiking each bite. My recipe goes a bit wild with all the savory bits, but trust me, you want it this way!

The preparation takes a bit of time to explain, but you'll see down below that it is actually quite easy to put together. That being said, this is a bit of a time suck, so feel free to prep bits and pieces over a couple of days. You can also freeze the cooked puddings. Just defrost them thoroughly (overnight in the refrigerator is best) before slicing and frying.

Radish cakes
Luóbō gāo 蘿蔔糕
Guangdong cuisine
Makes 2 large loaves, serves 12 or more

Cut up some radish batons
Cakes:
¼ cup | 30 g dried shrimp
Boiling water
About 4 pounds | 2.5 kg very fresh Chinese or Korean radishes, or daikon
12 black Chinese mushrooms, soaked until plump
6-inch | 15-cm strip of Cantonese-style cured pork belly
2 Cantonese-style sweet sausages of any kind
About 6 ounces | 170 g shallots, finely chopped
4 cloves garlic, finely chopped
1 cup plus 2 tablespoons | 170 g regular rice flour (not sticky/sweet/glutinous rice flour)
Reserved cooled mushroom soaking water, plus more cool water as needed to make 1½ cups | 375 ml
Lots of freshly ground black pepper (at least 1 teaspoon)
2 tablespoons regular soy sauce

Fry-up and serving:
Cornstarch, as needed
Fry the charcuterie
Peanut or vegetable oil, as needed
Flaky sea salt (like Maldon), for garnish
Chopped scallions or cilantro, for garnish

1. Place the dried shrimp in a heatproof boil and cover with boiling water; let them plump up while you prepare the rest of the ingredients, and then drain and dice coarsely.

2. Trim and peel the radishes. Cut them up to make 2 cups | 275 g of batons (around ¼ inch | 5 mm on 2 sides, and no more than 1 inch | 2 cm long), and coarsely grate the rest. Remove and discard the stems from the mushrooms, and then chop the caps into ¼ inch | 5 mm pieces. If the cured meat and sausages are at all hard, steam them for around 10 minutes to soften them up; reserve any juices and add them to the batter later on. Remove and discard the skin from the pork belly, and then chop it as well as the sausages into very small pieces about the size of lentils. Finely chop the shallots and garlic. 

Rice flour, but not the sticky kind
3. Measure the rice flour into a medium work bowl, and then stir in the water to form a thin batter. Line the bottom of 2 large loaf pans with parchment paper so that the sides extend above the top. Grease both the paper and the insides of the pans. If you are not using a bamboo steamer basket, wrap the lid with a kitchen towel so that moisture doesn't drip back into the cake while it steams.

4. Place the chopped cured meats in a cold wok and fry them over medium heat so that the fat is rendered as the meat cooks. Once the fat is translucent, add the diced shrimp, mushrooms, shallots and garlic, and stir-fry them over medium-high heat until the mushrooms have shrunk down and started to brown a little bit. Scoop the meat mixture out of the wok and into a work bowl.

5. Turn the heat under the wok to high. Add all of the radish shreds and batons to the wok. Sprinkle the black pepper over the radishes, and then cook them, tossing occasionally, until quite a lot of liquid forms at the bottom of the wok and the radishes are completely cooked but not at all mushy. Toss the meat mixture in with the cooked radishes, reserving, if you like, a few tablespoons of the meaty crumbles as decoration later on. Taste the radish-meat mixture and adjust the seasoning, if necessary.

The steamed pudding
6. Remove the wok from the heat and stir the thin batter into the cooked radishes. Gently toss the radish with the batter off of the heat so that the bottom does not scorch. After about 30 seconds, the residual heat in the wok should cook the batter enough so that it starts to thicken. When everything is completely combined, scrape into the prepared pans. Sprinkle on the optional reserved meat mixture, and then use the parchment paper ends to compact the mixture and smooth down the top.

7. Heat a few inches of water under your steamer until it comes to a full boil. Either position the pans on a large trivet and cover them with the wrapped lid, or place the pans in covered bamboo steamer baskets. (You may need to steam the pans separately if your steamer is not large enough.) Steam the pudding for around 90 minutes to 2 hours, replenishing the water as needed, but otherwise not opening the lid, as this will help to cook it evenly. Test to ensure it is completely done through by inserting a paring knife into the center; it should come out clean. Remove the pans from the steamer and allow them to come to room temperature before covering the pans with plastic wrap and refrigerating.
... and then fry it up

8. To serve, slice the chilled pudding into either 1-inch | 2-cm cubes or into 1-inch | 2-cm thick slices. Coat them completely in cornstarch and shake off any excess. Prepare a serving platter by the stove and cover it with a few sheets of parchment or tempura paper. Heat about ¼ inch | 5 mm of oil over medium-high heat in the bottom of a flat-bottomed pan until a pinch of cornstarch immediately foams and subsides, and then add the dusted cubes to the hot oil piece by piece. Fry them all over, adding more oil as needed. When they are a golden brown, remove to the platter. Serve hot sprinkled with sea salt and fresh cilantro and/or chopped scallions. A dipping sauce may be prepared, but is not necessary.

Mushroom turnovers

One of my all-time favorite cookbooks was written by one of my all-time favorite people: FlorenceLin’s Complete Book of Chinese Noodles, Dumplings and Breads. Now in her mid-nineties and living in upstate New York, Auntie Shen (that’s what we call her) is still as vibrant and funny and full of delight with the world as she’s always been.

I love her book because it is so reliable and so full of the things I adore eating. Very trailblazing for its time, her cookbook covers a lot more than just Cantonese cuisine, and instead travels over much of China in a quest for great things to cook and serve. So, if you have lived in places like the Mainland or Taiwan for any amount of time, or if you are a sophisticated diner, you will find many of your most beloved dishes in here.

Auntie Shen
Auntie Shen recalled her recipe for curry beef turnovers during one of our endless conversations about food. In between peals of laughter, she told me about how she made endless batches of these back when she lived in New York City, and Craig Claiborne even mentioned them when he wrote an interview with her. She included this recipe and the story in her Chinese Noodles cookbook, of course. What I want to mention right here is that the recipe right after that one is for her mushroom puffs. (Both of them are of course incredibly delicious.)

Over the years I’ve made some adjustments to these already perfect recipes in my search to make them more the way that I used to enjoy them in Taipei’s and Hong King’s dim sum parlors back in the day. No matter what else got tossed or added, I have always preserved one of Auntie Shen’s secret weapons: mashed potatoes.

Mashed potatoes
Probably a holdover from these little turnovers’ ancestral roots as Indian samosas (after all, that’s what they are), the mashed potatoes insert a lovely creaminess into the mixture and also hold things together admirably while you are crimping the pastry together. I wouldn’t have it any other way.

This recipe makes 8 dozen, which seems like a lot, but I always double it, especially this time of the year when we find ourselves at so many parties, both here and at friends’ homes. That’s almost 200 little turnovers. I know. But they can be made over a day or a week, and they are vegetarian, which solves lots of guest preference problems right then and there, since just about anyone who can eat wheat can then enjoy them.

The mushroom filling
I freeze the puffs right after I shape them, and then dab them with an egg glaze before popping them in the oven a few minutes before the guests arrive. They end up being incredible holiday lifesavers, and they never fail to please.

Mushroom turnovers
Xiānggū yóusū jiăo 香菇油酥角
Hong Kong
Makes 8 dozen
  
Filling:
1½ ounces | 40 g dried black mushrooms
Water, as needed
1 medium | 150 g Yukon Gold potato
2 tablespoons toasted sesame oil
2 tablespoons unsalted butter
2 cloves garlic, finely minced
1 tablespoon finely minced ginger
Cut out the rounds of dough
1 medium | 150 g yellow onion, finely diced
3½ ounces | 100 g winter bamboo shoots, fresh or defrosted, finely diced
2 tablespoons Shaoxing rice wine
2 tablespoons regular soy sauce
1 tablespoon sugar
2 tablespoons finely minced yacai preserved vegetable or winter vegetable, optional
Freshly ground black pepper
½ cup | 60 g toasted sesame seeds

Pastry:
4 cups | 600 g all-purpose flour, plus extra for rolling out the dough
1 teaspoon sea salt
¾ cup | 115 g | 1½ sticks unsalted butter, chilled
¾ cup | 120 g white shortening, chilled
About ⅔ cup | 160 ml chilled water

Spray oil
1 large egg lightly beaten with 1 teaspoon water

Marbles of filling
1. Start this recipe at least 2 days ahead of time. First make the filling: Soak the mushrooms in cool water overnight. When they are fully plumped up, gently squeeze them dry, remove the stems, and chop the caps into a fine dice. Cut the peeled or unpeeled potato into 1-inch | 2 cm cubes, and boil the chunks until you can flake them with a fork. Drain the potato and mash it.

2. Set a wok over medium heat before adding the sesame oil and butter. When the fat starts to shimmer, add the garlic, ginger, and onion. Stir these around and cook them gently until the onions take on a golden tinge. Add the mushrooms, bamboo shoots, rice wine, soy sauce, sugar, optional yacai, and lots of freshly ground black pepper. Cook these together until the liquid has been absorbed and the vegetables are cooked. Remove the wok from the heat and mix in the mashed potatoes and sesame seeds. Taste and adjust the seasoning. Cool the mixture to room temperature and then chill it.

Into the freezer they go
3. Next make the pastry: Mix the flour and salt together in a large bowl or food processor. Cut the butter and shortening into small pieces, toss them with the flour, and then either cut the fats into the flour or pulse them together until the fat is pea-sized or smaller, but be sure not to overwork it. Quickly toss in or pulse in the ice water to form a dough; don’t add any more as soon as you see it sticking together. Turn the dough out onto a smooth work surface. Use the heel of one hand to smear out small handfuls of dough, and use a pastry scraper in the other hand to gather it all up into a mound. Repeat this one more time to turn the fat into flake-forming layers in the dough. Divide the dough into 4 even pieces, shape these into rectangular pillows, wrap in plastic, and chill, preferably overnight, as this will give the flour time to absorb the liquid and the gluten to relax.

4. Working on one piece of dough at a time, lightly sprinkle your work surface and the piece of dough with flour. Roll the dough out until it is about 12 inches | 30 cm square. Use a round 2½ inch | 6 cm cutter to stamp out as many circles as you can. Cover the dough circles with a clean tea towel and repeat with the rest of the dough until you have about 96 pieces. You can combine the raggedy scraps as you go and use those, as well. Store the dough in the refrigerator if your kitchen is hot, and always keep the dough covered to prevent it from drying out and cracking.
 
An egg glaze makes these glossy
5. Have a few baking sheets ready and line them with plastic wrap. Set up your work area with the bowl of filling, a small spoon, a small bowl of cold water, a fork, and a damp towel for wiping your hands as you go. To wrap the turnovers, wet a finger and run it around the edge of a dough circle to help it seal tightly later on, and then set a ¾ inch | 2 cm marble of filling in the center. Close the dough over this to form a half-moon shape. Press the edge closed with your fingers, and then crimp the edge with a fork. Place the finished turnover on a lined sheet. Repeat with the rest of the filling and dough. Try not to allow the unbaked turnovers to touch so that they don’t stick together, and lay another piece of plastic wrap on top if you want to freeze two layers at the same time. Set the sheet in your freezer, and then later on pop the frozen turnovers into a resealable freezer bag.

6. To bake these, place a rack in the center of your oven and set it for 400°F | 200 °C. Line a baking sheet with Silpat, foil, or parchment paper and spray it with oil. Place as many of the frozen turnovers on the pan as you want to serve and brush the tops with the egg glaze. Bake the turnovers for about 12 to 15 minutes, or until golden brown. Serve hot.

Perfect pie crust, or Hong Kong custard tarts part 1

Chinese custard tarts are one of my favorite things ever. 

I love the creamy, delectably spotted ones from Macau that sit proudly in their puffy nests, and I love the shiny, eggy, golden ones from Hong Kong with their mirror-like tops and piecrust pastry. 

These two kinds of custard tart are, therefore, totally different, and pretty soon I’ll crack that Macanese custard tart code for you. 

Right now, though, we are going to dive into Hong Kong’s mini masterpieces. They are a whole lot easier than they look, but you will have to pay attention. This is pastry, after all.
Pastry cutter & wooden bowl

Dear reader, this is the first half of a recipe I have been searching for and never, ever finding. I made so many bad batches that my poor husband wondered how many eggs we'd plow through before I was finally happy. Well, I'm officially happy.

What happened was, that one day I’d finally had enough. I couldn't stand in long lines at my favorite Chinatown bakeries forever whenever I wanted a danta fix. I had too much writing (read: eating) to do. 

Furthermore, I decided that I wouldn’t wear a swimsuit this year if it meant that I could find that perfect mesh of flaky piecrust and delicate filling. 

Some sacrifices are worth making.

I tried all sorts of piecrusts in my odyssey… cookie-like, puff pastry, lots and lots of regular piecrusts… but none really hit that sweet spot. 
Tossing the flour, fat, and liquids

I knew it would in the end have to be nothing less than good old homemade piecrust, but I sort of dreaded that. I even resorted to frozen piecrust in a vain attempt to end-run the inevitable, but those store-bought things never worked out well or tasted right.

The thing is, I had always been rather afraid of the whole making-your-own-piecrust ordeal because the crust inevitably turned out leaden, no matter how hard I tried. 

Then a while ago I bought a copy of The Gift of Southern Cooking by Edna Lewis and Scott Peacock, and it rocked my little world. 

I used that beautiful book to understand the art behind making the perfect piecrust, although the ingredients below more or less follow the guide enshrined in Michel Roux's Pastry. However, as always, I’ve added more details (and made a few small tweaks) to the final recipe so that you can become as fearless as me when it comes to piecrust.

Clumped up and ready to smear
What I finally figured out was that I was not supposed to make pie dough. The name is what slipped me up, because I was always doing my best to make a doughy mass that I’d faithfully chill and try to roll out and always end up wanting to throw at the wall and that had the consistency of cardboard and was an utter waste of time.

The secret here is to not think of this as dough. And to not make it in a food processor.

Rather, what you are going to do is simply incorporate some good, chilled fats and an egg into unbleached all purpose flour, add just a sprinkling of ice water to encourage things to come together a bit, and then smear this mixture out into thin skids on the counter, which is what turns everything into flaky layers.

Again: Do this by hand, not in a food processor. You need nothing more than a pastry cutter and, in my case, a wooden bowl to keep things happily corralled. This way you can ensure that the bits of fat are cut into the right size, rather than mashed into oblivion. Larger pieces of cold fat will melt in the heat of the oven into airy layers between the flour before frying the flour into heavenly crispiness. The eggs are important, too, because they make the crusts a tad more solid and stable.
First smear

I've talked to a couple of bakers who do little else but make custard tarts for a living. Granted, most people didn't want to discuss their secrets, but a few kinds folks let slip the fact that the crusts they use come premade. That's where those little tiny Chinatown tart tins come in to play. I'm guessing that someone puts out millions of those ready-made crusts, freezes them, and then sells them to bakeries, restaurants, and dim sum parlors, because they generally taste the same no matter where you get them. In other words, these piecrusts do the job, but tend to be pretty generic.

You can therefore up your danta game considerably by making something homemade and ever-so-much-more delicious.

I've suggested that you use all-metal muffin tins here instead of those usual little aluminum tart tins favored by Chinatown bakeries. This will give you a bit of a deep-dish tart with more ratio of custard to crust, which in and of itself is a glorious thing. The heat the tins concentrate on the bottoms and sides will also give you crispier, crunchier crusts.
After two smears

You will need around 2 cups (about 500 ml) dried beans or an equivalent volume of pie weights for the occasion because the crust will swell up during the initial baking (aka blind baking), and so the beans or weights these will hold the fort down nicely. If you don't weigh down the raw crust, or if you don't blind bake the shells, you run the risk of having the bottom crust balloon and push all your custard out of the pan, which would be sad. As for me, I have an ancient mayo jar with shriveled garbanzos in it that follows me wherever I move, and it has pride of place on my pantry shelf.

Do note that while it is conceivable that you can use silicone muffin pans here, since they make removal of the tarts from the tin a whole lot easier; the down side is that the crust won't crisp up very well. Whatever tin you use, be sure and spray it with oil, as this helps prevent the crust from welding to the pan.

Try this recipe and see if you become a convert. Next week we’ll do the filling. But first I want you to master piecrust and never fear making a pie again.
Beans & parchment paper

If you are a purist and are wondering why you should be making these tarts with a Western-style crust, remember that Hong Kong-style custard tarts were most probably introduced to Guangzhou (aka Canton) by the Brits, and good old custard filling is definitely an Anglo-American delight, so I'm just carrying on this grand tradition of cultural and culinary cross-pollination...

Flaky piecrust
Sūpí  酥皮
Southern China by way of the Southern U.S. and France and other good eating-places

2½ cups (375 g) all-purpose flour (see Tip)
1½ teaspoons sugar
1 teaspoon sea salt 
1½ sticks (¾ cup / 170 g) unsalted butter, chilled
1 large egg plus 1 large egg white, lightly beaten
1½ tablespoons ice water
Spray oil
1 large egg white beaten with 1 teaspoon water

Layers of fat = airiness
1. The crust: Start this recipe at least a couple of hours before you need it. Mix the flour, salt, and sugar in a wide work bowl. (I like to use my ancient wooden salad bowl for this.) Cut the fats into the flour using your pastry cutter until you have pieces no larger than ½ inch (1 cm) across), but don’t cut it too fine.

2. Use one hand to gently toss the flour as you sprinkle in the eggs to combine it, and then toss in the ice water, a teaspoon at a time. Curl your fingertips up as you do this so that you are gently mixing things up, rather than mashing them. (The second biggest cause of piecrust failure is overworking the dough or using the palm of your hand, which is way too hot for this work.) To test it, press a handful in your fist, and it should clump together. Only add a few tiny more dribbles of water if necessary. (The biggest cause of failure here is adding too much water. Don’t worry if there are some dry areas, as the next step will take care of that.)

Roll out between plastic
3. Dump the mixture out onto a clean, smooth work surface and have a pastry scraper ready. Pick up a small handful about the size of an egg and then use the heel of your hand to smear it away from you. This is where you start to form layers in the piecrust. Repeat this with the rest of the mixture. Then, use your pastry scraper to form this into a rough mass before repeating this step. You will find that everything will be pretty willing to stick together when you are finished. Form the piecrust into a raggedy disc and place it in a resealable bag; you'll have a little over 1½ pounds (720 g) of dough at this point. Refrigerate the piecrust for at least 2 hours so that the flour can absorb the water and expand, and the gluten has a chance to relax.

4. Spray your muffin tin with oil. Lightly dust your work area with some flour, place the dough in the center, and dust it with a bit more flour. Cut it into 12 even pieces and then roll them into balls. Working on one ball at a time, place a ball between two sheets of plastic wrap and use a Chinese rolling pin roll it out into a disc about 5 inches (13 cm) wide. Set the circle into a muffin tin cup and gently pat it to fit. Repeat with the rest of the balls. 

Pat into the muffin tins
5. Next, dip the end of your rolling pin in flour and gently tap the dough into each tin, pressing against the bottom edges, and then rolling the pin around any uneven parts on the sides. Freeze the muffin pans for at least 20 minutes, as this will help the crusts keep their shape.

6. Heat your oven to 425°F (200°C) and set an oven rack in the center. (Do not use the convection or fan setting for this recipe.) First you will blind bake the crusts, which will set their shape and ensure that they have enough time to crisp up during the final baking: lightly prick the bottom of each tart with a fork to help keep the bottoms from rising too much. Refrigerate the piecrusts until you are ready to bake them.

7. Completely cover each shell with a 5-inch (13 cm) square of parchment paper or foil so that they do not brown during this step. Also, be sure and fit the covering into the bottom corners of the tarts since this will keep their shape. Fill the shells with your pie weights or beans, again paying special attention to the corners. Pour boiling water into any empty depressions. Bake the shells for about 5 minutes, and then rotate the pan from front to back and bake 2 minutes more. The shells will be set at this point, but not yet browned.

8. Remove the beans and coverings from the shells. Prick (also called "dock") any bubbles that you see, and then coat the insides of the shells with the egg white mixture. Since the custard filling is very wet, this last step will create a nice, waterproof seal in the tarts and prevent the crusts from sogging up. 

Dock the shells
9. Return the shells to the oven until they just begin to color, about 3 minutes. You do not want to brown them at this point, so keep a careful eye on them and rotate the pan as needed. Remove the pan from the oven. (If you are going to bake the custard tarts immediately, reduce the oven to 275°F / 135°C and wait until it cools down to this temperature, since the custard requires a gentler heat than the crust in order to set up properly. If the oven is too hot, the custard will boil, which means that instead of that seductively satiny texture, it will be coarse and have bubbles running through it.)
Now you’re done and ready to fill the shells. You can freeze them at this point and then store them in a plastic container in the freezer so that they don’t break. You don’t have to defrost them before baking.

Tip

Use unbleached all-purpose flour here, as it has a higher protein content, which gives the raw crust more elasticity.
