Heaven on a plate

In this salad, the ingredients sparkle and refract colors like a stained glass window.  There's a rich combination of opaque, transparent, and solid hues that give depth and texture to its beauty.

But that's not all.

The scent of the sea imbues each bite, and yet this is not overwhelming... it's not low tide on a plate.  Rather, there's that characteristic balance that is the hallmark of any great Chinese dish.  Crunchy agar strips may taste bland, but they also lighten the flavors, and they are as clear as glass.  Thin cucumber ribbons too play a supporting role here, but they offer a freshness and almost a melon undertone to each mouthful.  A sprinkle of toasted sesame seeds provides a nutty punch, and this is probably the last flavor to remain on your palate, while the sparkling red Chili Oil punctuates the first barrage to hit your taste buds. You might be working with two of these ingredients for the first time here, so let me introduce them to you.

Agar strips
First up are the agar strips.  Agar comes in many forms - in blocks and as powder, as well as noodle-like strips - and is made out of a type of seaweed that has been processed into its present state.  So, agar (or agar-agar or yangcai or kanten) is in fact just another variety of sea vegetable that's showing up in today's mix.  Do be aware that once it's soaked, dried agar blooms into many times its original size, so don't be too enthusiastic about reconstituting the entire package.

In this recipe, you only need to cut off about a quarter of the skein, and the rest can be packaged back up and saved for another day; it will keep pretty much forever if stored in a dry and bug free place.

Agar needs minimum processing when it is used in cold dishes.  All you have to do is rinse it, soak it in cool water for a few minutes, and then in hot tap water for about another five, and then rinse it again in cold water.  What this does is wake up the agar, softening it without melting the strips, and then snapping it back into shape again.  As you do this, watch the agar turn from hard pieces that look like dried cellophane (fensi) noodles into flexible whitish strands, then into a clear soft tangle, and then into translucent lengths that are once more firm.  It's entertaining, or at least for me it is.
Agar as slithery strips

Next up are the sea vegetables.  You can use plain seaweed if you wish, but look around for mixed sea vegetables, since they offer lots more variety, whether in taste, color, or shape. You sometimes can find them fresh, but they are more commonly sold packed in salt in little bags; a health food store is a good place to find them.  Keep these packages sealed and in the refrigerator until it's time to use them.  Then, just rinse the sea vegetables under running cool tap water to wash off the salt, soak them in some cool water to reinvigorate them, and then drain the vegetables thoroughly before adding them to your salad; they shouldn't be cooked or even blanched.

This recipe could easily be from any area along China's coast, so it's hard to say where this salad originally hailed from, but it is enough of a culinary chameleon to fit in just about any cuisine.  The sprinkling of red hot Chili Oil only serves to disturb the search for its lineage, but I offer it to you anyway in the hopes that you love this jewel of a salad as much as I do.

Spicy sea vegetable salad 
Hóngyóu hǎicài shālā  紅油海菜沙拉 
Eastern China
Serves 6 to 8 as an appetizer

About ¼ of a (1.5 ounce) package of agar strips
8 ounces (or so) mixed sea vegetables packed in salt
1 small Persian cucumber, julienned
½ teaspoon sea salt
2 tablespoons light-colored, flavorful vinegar
2 tablespoons sugar
1 clove garlic, minced very finely
Chili Oil to taste, or roasted sesame oil to taste

Cut up the dried agar
1. Use a pair of scissors to lop off that piece of agar strips and wrap up the rest for some other time.  Place the strips in a colander and rinse under cool running water to remove any dust or debris.  Place the strips in a work bowl and cover them with cool tap water for a couple of minutes, drain, and then cover with hot tap water for another 5 minutes to fully reconstitute them.  Then, drain the strips and rinse them with more cool tap water.  Cut the strips into 1-inch lengths and drain well.

2. Rinse the sea vegetables in a colander with cool tap water and then place in a work bowl.  Cover the sea vegetables with cool tap water for a few minutes to wake them up, and then drain thoroughly in a colander.

3. Place the agar, sea vegetables, and cucumber in a clean work bowl with the salt, vinegar, sugar, and garlic.  Mix together, adjust the seasoning, and refrigerate for at least an hour.  Just before serving, taste again and add more salt, sugar, or vinegar as needed.  

4. Pile the salad on a pretty plate, sprinkle with Chili Oil or sesame oil, and dust the top with the sesame seeds.  Serve cold as an appetizer or side dish in hot weather.

Cool salad for a hot spring day

Jicama is an odd tuber. It seems rather unsure what it is: too sweet to be a regular old root vegetable and too subterranean to be a fruit, it comes across as a strange interloper in the plant community.

But I do like it. That sweet crispness more than makes up for its weirdness, and although I often fail to see jicamas in the market -- stored as they are with the other root vegetables, I'm always making a beeline for the garlic and ginger, I guess -- they never fail to please me once I decide to work with them.

This is definitely one root veggie that is better raw than cooked. In fact, I don't think I've ever been even tempted to apply heat to a jicama because in their raw state they are just so delicious. Peeled and cut into sticks, jicama is a perfect snack combining all the sweet juiciness of a pear with the healthy appeal of a vegetable.

Shanghai has a lovely take on jicama that does justice to its character, and as the days heat up, this is a nice dish to have stashed in the fridge as a quick and refreshing side.

The brilliance of this dish has to do with the textures. In addition to the crunch of the jicamas, there's also the slithery appeal of the agar. This appetizer is sometimes made with thick green bean noodles (dongfen), but they are no match for the gentle resilience of the agar. Besides, agar is just so pretty, standing out like crystalline strands against the opaque white.

Softened agar strips
No cooking or even hot water is required here, merely some slicing and dicing. Plan on marinating the salad for at least a couple of hours so that the dressing and the veggies get a chance to meet and greet. I like to put this together in the morning, as it will be just perfect for dinnertime. Leftovers will keep another day or so if refrigerated, but always add the cilantro at the last minute, as it will just wilt and lose its startling green color if exposed to acid (i.e., vinegar) and salt.

Jicama has a couple of different names in Chinese. Digua (ground squash) is the most common, but it occasionally is referred to as yangdigua (foreign ground squash), since the majority of vegetables that migrated into China have yang (literally "ocean," meaning that it came overseas, like yangcai or agar), or hu (literally the name of the non-Han nationalities in the Chinese northwest, so something that is introduced over land, like hujiao or black pepper), or fan (foreign, like fanqie or tomato).

Lots of history in a name!


Sweet and sour jicama salad 
Tangcu digua 糖醋地瓜  
Shanghai
Marinate the veggies
Serves 6 to 8 generously as an appetizer, 4 to 6 as a side dish

0.5 ounce dried agar strips (a bunch about 1 inch thick and 12 inches long)
Filtered cool water as needed1 small (12 ounce) jicama (see Tips)
2 red jalapeno peppers (or to taste)
1 tablespoon sugar, or to taste
5 tablespoons white rice vinegar, or to taste
½ teaspoon sea salt, or to taste
10 or so sprigs of cilantro, stems removed

1.  Place the agar strips in a large work bowl and cover with the cool tap water while you prepare the rest of the ingredients.

2. Peel the jicama with a potato peeler, and be sure to remove any tough webbing underneath the brown skin. Trim off the ends of the jicama and cut the tuber in half. Cut it into ¼-inch slices, and then across into ¼-inch strips. Place the jicama strips in a work bowl.

3. Remove the caps, seeds, and interior ribs from the jalapenos before cutting them into very thin strips. Add the jalapenos to the jicama.

4. When the agar is soft and transparent, drain it thoroughly before cutting it into lengths that are about the same size as the jicama. Add to the bowl with the jicama.

5. Sprinkle the sugar, vinegar, and salt over the salad and toss well. Cover and refrigerate for at least a few hours. Just before serving, carefully rinse and dry the cilantro, and then chop it coarsely. Toss it into the salad, and then taste and adjust the salad's seasoning. Serve chilled or just slightly cold.

Tips

Choose jicamas that are hard and feel heavy for their size. Avoid any with mushy spots or shriveled stem ends. 

Refrigerate any jicama that you do not use right away, and keep them very dry, as water can cause rotting.

Feel free to use any kind of chili pepper that you enjoy. If you are serving children or people with no tolerance for heat, try substituting red bell peppers or fresh pimentos.  

Agar strips can be found in most East Asian groceries, as well as in some health food stores. It keeps practically forever if sealed in an air-tight bag.
