If you have felt apprehensive upon approaching the fish counter—whether you don’t have much experience cooking fish or you just made eye contact with a finned fellow lying there on the ice—you’re not alone.
“I would say [people feel] terrified,” Mark Usewicz, one of the founders of the Brooklyn seafood shop Mermaid’s Garden, told me, for a few reasons:
They’re worried about their house smelling fishy, or they don’t know what to expect from a certain fish. Or they just feel uninformed about what cooking seafood entails beyond the occasional filet of salmon or halibut.
The first steps to bolstering your fish-counter courage? Find a fishmonger you trust and “Ask your fishmonger questions,” Mark said. These are the ones you should start with.
“A lot of people don’t realize that most fish have seasons,” Mark said. Right now, for example, if you live in the Northeast, you should look into monkfish and skate, which aren’t as good once the water warms up.
This might mean that you have to adapt a recipe—but luckily, most recipes adapt easily to other varieties of fish. This comes with the added benefit of having an opportunity to try a lot of different kinds of fish. “We don’t sell farmed salmon, so we only have salmon from late spring to early fall,” Mark said. But there are lots of seasonal, responsibly farmed fish that make great stand-ins for salmon, like red rainbow trout and arctic char. “They’re both in the salmon family, and they’ll cook the same way,” said Mark.
These questions are a good way to gauge both how fresh the fish is and how knowledgeable your fishmonger is. Don’t be afraid to ask where the fish came from and how it was caught (by spear? by net? by trawl?). Ask if it came in from a big industrial fishing fleet, or a fisherman-owned boat. “A lot of big boats go out for weeks at a time, while the little guys go out overnight,” Mark added—so that will affect how long it’s been since your fish was pulled out of the water.
While you’re thinking about freshness, check out the fish case: Is there a fishy smell in the air? (If so, bad news.) The fish filets should look firm. The whole fish should look shiny, with clear, bright eyes; the gills should be reddish. Mark advised that you should “be suspect if the gills are pulled out of whole fish”—it’s a sign the seller is trying to hide how fresh the fish is.
