Cooking Seafood Safely: Doneness & Brining

Shellfish Doneness Window

Shellfish are perfectly cooked in a narrow window: undercooked they are translucent, overcooked they turn rubbery and shrink.

Example: shrimp are done when just pink and opaque (about 60–63°C); scallops when the centre is still translucent; mussels as soon as they open.

Seafood Brining Logic

Briefly salting or brining fish and shellfish (about 10–30 minutes) to season them and firm their texture, without turning it into a cure.

Example: salmon fillets brined for 10 minutes in 5% salt water push out less albumin; shrimp brined with a little baking soda stay plump and snappy.

Fish Carryover Risk

Fish keeps cooking after it leaves the heat, and because its proteins set at low temperatures it goes from moist to dry very quickly.

Example: take salmon off at about 46–48°C so it rests to a silky 50–52°C; halibut becomes chalky if cooked past about 55°C.
