Guidelines for Cooking Shellfish
- Fish—Cut through the side of the fish and open it up to expose the flesh. The inside should be opaque and separate easily.
- Shrimp and lobster—When cooked, the flesh should be pearly-opaque.
- Scallops—The flesh should look milky white/opaque and firm.
- Clams, mussels, oysters—When the shells open, they are done. Throw out any ones that do not open.
