How to Determine When Fish is Cooked
Fish is done when it looks opaque and flakes easily with a fork. Undercooked fish looks translucent, while overcooked fish looks dry and falls apart.
Buying and Storing Frozen Fish & Shellfish
When purchasing frozen fish or shellfish, make sure it is well wrapped and solidly frozen, with no odor. Always check the "sell-by" date on the package. Avoid fish that has been thawed and refrozen. Store it in the refrigerator, tightly wrapped, for up to 2 days. Never refreeze fish or shellfish once it's been thawed.
