There are several ways to determine if your fish is cooked properly. One common method is to check the internal temperature using a meat thermometer. For most fish, the internal temperature should reach 145°F (63°C) when fully cooked. Another way is to use the flake test: gently insert a fork into the thickest part of the fish and twist. If the fish flakes easily and the flesh is opaque, it is done. Additionally, you can observe the color of the fish; it should be opaque and easily separate with a fork. Overcooking fish can result in a dry and rubbery texture, so it's important not to overcook it. Remember that residual heat will continue to cook the fish even after you remove it from the heat source.
