Fukagawadon (深川丼, Tokyo clams in miso broth over rice)

Asari are small clams, and small clams are honest. In spring, when they're at 旬 (shun), at their prime, each shell carries its own clear liquor. You don't need a heavy hand, only dashi, miso, a little sake, and rice waiting in a bowl. If the clams smell tired or sit open and won't close when tapped, choose another dish. Nothing hidden.

Fukagawadon looks like comfort food because it is: broth poured over rice, scallion softening in the bowl, clams opening one by one. The name points to Fukagawa, a canal-bound part of old Edo where this was working food, not ceremony. The surprise is how little technique it asks. Make a clear dashi, open the clams just until they give up their juice, then dissolve the miso off the boil so its fragrance stays bright.

The one thing to watch is the clam. It is done the moment the shell opens. After that it shrinks and turns chewy, which is a poor reward for impatience. Ladle the broth generously, but don't drown the rice. We want a bowl that eats clean, with the sea in the broth and the rice still rice. That is 本物 (honmono), the real thing, made reachable in one pot.
