Frozen fish can be just as tasty as fresh when cooked correctly. The main goal is to preserve moisture, prevent sticking, and avoid overcooking.
How to cook frozen fish correctly
To cook frozen fish correctly, do not thaw it first, use moderate heat, add moisture, and extend cooking time slightly compared to fresh fish.
Why frozen fish often turns dry
Frozen fish contains ice crystals that release water during cooking. High heat evaporates this moisture too quickly, leaving the fish dry.
Incorrect thawing also damages the muscle structure, making the fish fragile.
