Scallops

Fresh scallops keep only 1–2 days refrigerated — one of the shortest windows at the counter — and 3–6 months frozen.

Store them in a covered dish over ice, and pat them dry before storing. Scallops sitting in accumulated liquid deteriorate noticeably faster.

It is worth knowing which kind you have bought. Dry scallops are untreated. Wet scallops have been soaked in a sodium tripolyphosphate solution, which makes them absorb water — they weigh more, look opaque and bright white, leak liquid in the pan, and refuse to brown. Dry scallops are ivory or faintly pink, slightly translucent, and sear properly. The distinction affects cooking more than safety, but wet scallops also hide their age better, since the added moisture masks texture changes.

Freeze scallops in a single layer before bagging so they do not fuse into a block.

Scallops are the adductor muscle of a bivalve — the muscle that holds the shell closed — and they are almost pure protein with very little fat or connective tissue. That composition is why they cook in ninety seconds, and also why they spoil so fast.

With minimal structural collagen to hold them together, scallops lose integrity quickly as their own enzymes work on the muscle. They turn from firm and springy to soft, then to distinctly mushy, and the surface goes slick. That texture change is the most reliable indicator you have.

Because scallops are shucked at sea and sold as bare muscle, they get none of the protection a shell provides, and unlike clams and mussels there is no liveness test available. They are simply perishable seafood on a very short clock.

Fresh scallops smell sweet and faintly of the ocean. A sour or ammoniac smell means discard — the same rule as for shrimp and crab, and for the same chemistry.

One point of confusion: a slightly orange or coral tint is roe, which is normal and edible. Uniform bright white is more often a sign of phosphate treatment than of freshness.

The date on a seafood package is almost never a safety deadline. A "sell by" date is an inventory instruction for the store. "Best if used by" is a quality estimate.

Neither overrides refrigerator windows from FoodSafety.gov / FDA seafood guidance. Fresh seafood bought on its sell-by date still needs cooking or freezing within the cold-storage window on this page. Freezer times here are quality windows — food held at 0°F stays safe longer, but texture and flavor fade.
