The French love to cook fish by poaching it in a flavored liquid, usually a combination of white wine and water, leeks or onions, and some herbs. It’s a notably lean way to roll because there’s no fat involved. And the finished product is reliably tender because it’s been cooked at a low temperature.
So, it’s lean, tender and … quite boring. I crave more flavor and texture. So here’s a recipe for poached salmon that adds the missing elements.
Typically, poaching calls for a lot of liquid. The fish is supposed to be submerged as it cooks, after which the liquid usually is tossed. I wanted a way to poach the fish in a small amount of liquid, which then could do double duty as a sauce. Given that fish generally requires a spritz of acid to brighten it up, the ideal liquid needed to be acidic and intensely flavored. Green salsa — that is, tomatillo salsa with chilies and lime juice — struck me as a likely candidate.
The salmon wouldn’t have to swim in a vat of the salsa. I made a modest batch and cooked the salmon in a smallish skillet with the salsa rising halfway up the sides of the fillets. I covered the pan tightly to trap the heat and flipped over the salmon halfway through its cooking time to make sure it cooked evenly.
