Fresh Lifted Yuba (引き上げ湯葉, Hikiage Yuba)

Yuba looks like a cook's trick until you see how little is happening. Soy milk is warmed in a shallow pan, left bare to the air, and a thin skin gathers on the surface. You lift it. That is the dish.

The one detail that decides it is the heat. Too low, and the skin forms slowly and weakly. Too high, and the soy milk scorches at the bottom or bubbles through the skin before it can set. Keep it just below a simmer, with the surface calm and faintly trembling, and the proteins and fats in the soy milk will do their quiet work. This is honmono made from almost nothing, which means the nothing must be good.

Use rich, plain soy milk, unsweetened and free of gums if you can find it. A tofu shop's soy milk is best, glistening fresh and faintly sweet, but a high-protein bottled one can teach the method honestly. At the table, serve the sheets warm or cool with shoyu and a little wasabi. Leave them room. Yuba is delicate enough that a heavy sauce would only announce that the cook has stopped listening.
