Delta Fish Curry

Nga hin is what the Ayeyarwady delta cooks when nobody is celebrating anything — the daily curry of a landscape that is half water, where catfish and featherbacks come out of the same creeks that flood the paddy. If mohinga is the delta's festival of a breakfast, this is its plain Tuesday: firm steaks of river fish, a tomato-and-onion gravy stained deep gold, and the sheen of returned oil on top announcing the pot is done.

We file it under the Bagan era, and here is the honest version of why. No Bagan cook left us a recipe; what the eleventh-century record does show — in inscriptions and temple paintings — is the river economy this curry is made of: fish, rice land, turmeric, oil. The tomatoes are newcomers by comparison, arriving with the chili on later trade winds. The logic of the dish, a fisherman's catch simmered in whatever the garden gave, is as old as the delta itself, and nobody has improved on it.

Two techniques carry everything. First, the double turmeric — a rub on the fish to firm and sweeten it, a second measure in the base for the gravy. Second, the delta cook's signature restraint: once the fish goes in, you do not stir. You take the pan by both handles and swirl it in slow circles, so the gravy moves and the steaks do not. Do that, wait for the oil to rise red-gold through the tomato, and you have earned your rice.
