Frozen fish fillets

Mild and clean-tasting when recently frozen, flatter after long freezer storage.

Lens analyzed

Frozen fish fillets are cleaned, portioned, and frozen soon after the catch or processing, giving a convenient way to keep fish on hand without a trip to the seafood counter. Quality depends heavily on how quickly the fish was frozen after it was caught.

Where it comes from

Commercial fish freezing expanded through the 1900s as fishing fleets began flash-freezing their catch at sea, locking in freshness before the fish ever reached shore.

Buying it

Check the bag for a glossy, ice-free surface on the fillets — heavy frost or pale, dry patches usually mean freezer burn has set in.

Storing it

Keep it tightly sealed in the freezer, and thaw only what you plan to cook, ideally overnight in the fridge.

Keeps about 6 months in the freezer.
