After the sensory overload of Thanksgiving, all I want are the pure, soothing flavors of Japanese cuisine. Most Japanese recipes involve some combination of dashi, soy sauce, sake, and mirin, yet the sum of these few components is always greater than the parts. Aside from umami-intensive soy sauce, it must be all those free-flowing glutamates present in dashi that lend such complexity to each dish.
Most of the dashi I make goes towards miso soup and chawan mushi, the latter of which is not nearly as common in Japanese restaurants. Chawan mushi is an egg custard—the most delicate, ethereal egg custard I know of. The trick is to use as much liquid as possible in proportion to the eggs, which produces the soft, silky texture that's the mark of an impeccable chawan mushi.
"When properly made, the custard should be barely set and quivering."
When properly made, the custard should be barely set and quivering. We often use the word "quivering" to describe custard dishes, yet not all textures are delicate to such a degree. Crème brûlée, for instance, is not so much "quivering" as "creamy," and flan is better described as "jiggly." But chawan mushi truly quivers, a trembling mass of custard that seems to glide down your throat.
The Chinese make a similar egg custard from meat stock. Compared to chawan mushi, the Chinese version seems thick and clumsy. Both the Chinese and Japanese renditions start with a combination of eggs and liquid, steamed gently until set. But the Japanese version varies in two important ways. First, the proportion of liquid to eggs is much greater, such that the end result is impossibly silky. Second, the liquid for chawan mushi must be strained through a cheesecloth prior to being steamed.
These two procedural differences are key. Straining the liquid through the even finer sieve of a cheesecloth catches the wiry strands of egg whites as well as other potential impurities. Stretching out the eggs until the liquid is barely capable of congealing—more than two-thirds cup liquid per egg—is another attribute of the Japanese version that makes it so distinctive. Oftentimes, I've broken chawan mushi by adding one too many tablespoons of dashi, making it impossible for the eggs to congeal into custard.
It's never much of a problem to eat the mistakes. Chawan mushi is delicious even when it breaks. Instead of congealing, the eggs become suspended in the liquid, much like the appearance of miso paste in dashi. When this happens, the custard becomes a cloudy soup with a thicker yet airy texture.
Chawan mushi is best with additions of meat, seafood, and vegetables. Shiitake mushrooms, spinach, shrimp, and chicken are common additions to the custard, but many items pair well with the combination of eggs and dashi. I like to use enokitake, a long, thin white mushroom commonly available at Asian markets. Enokitake possesses a woodsy taste; added to the custard, the mushrooms are best when sautéed beforehand, which reduces the liquid content and concentrates the flavor of the mushroom.
Finally, chawan mushi is only as good as the dashi you use. Start with freshly made dashi for the most flavorful results. You'll know you've succeeded when your spoon slinks down into the custard; the tiniest amount of broth will exude, an indication that the mixture just nearly missed its breaking point.
For the Custard:
2 1/2 cups dashi
1 tablespoon soy sauce
1 teaspoon mirin
1/2 teaspoon salt
3 large eggs
Suggestions for Additions:
Half of a package of enokitake
4 fresh shiitake mushrooms
4 raw shrimp, shelled and deveined
4 ounces boneless chicken thigh
Beat the eggs lightly, then add the rest of the ingredients for the custard. Strain the mixture though a strainer fitted with one layer of cheesecloth.
Preheat a steamer over high heat. Have ready 4 bowls or lidded cups.
Place your choice of additions into the bottom of the cups or bowls.
For the enokitake: heat a heavy skillet and pour in a splash of olive oil or vegetable oil. Saute the enokitake in the skillet until golden brown, adding a bit of soy sauce or salt to taste. The mushrooms will exude quite a bit of liquid; let the liquid cook off for a few minutes as you brown the mushrooms.
Pour the liquid into the bowls or cups and cover with saran wrap or fitted lids.
Place the covered cups in the preheated steamer over high heat. When the surface turns white, about 3 to 5 minutes, reduce the heat to medium-low and steam for a further 15 minutes.
Test the custard by inserting a bamboo skewer or toothpick into the center. The custard is done when the liquid runs clear. The surface of the custard should be slick and moist.
Serve hot or chilled in the cup.
