Simmered Koya Tofu (高野豆腐の含め煮, Kōya-dōfu no Fukumeni)

Koya tofu is one of those ingredients that makes a new cook suspicious. It looks too dry to become tender, too plain to become delicious, and far too square to have much poetry in it. Good. This dish is here to prove otherwise.

Fukumeni means simmering so the ingredient takes seasoning into itself. That is the whole point. You don't coat koya tofu with sauce; you let it drink a pale dashi seasoned with mirin, sugar, and just enough usukuchi, light soy sauce, to keep the color gentle. Press it with chopsticks at the table and the broth should bead at the cut surface. That small glisten is the standard.

The one detail that decides it is the first soak. Rehydrate the blocks in warm water until the hard center is gone, then rinse and squeeze them gently between your palms. Too rough, and the sponge tears. Too little, and the old dried flavor stays where the dashi should go. Nothing hidden, nothing forced, only a quiet simmer and a patient ingredient doing what it was made to do.

This belongs beside rice, soup, and one sharper dish, often with greens or a vinegared thing nearby. It is make-ahead food by nature, better after it rests in its broth. Leave it room in the bowl, three pale pieces with a little green beside them, and the dish tells you exactly how much care went into it.
