Salmon is a delicate fish that can easily dry out if not cooked properly. There are a few key things to remember when cooking salmon to prevent it from drying out. First, always start with fresh, high-quality salmon. If you are using frozen salmon, make sure to thaw it properly before cooking. Second, be careful not to overcook the salmon. It should be cooked just until it is opaque in the center. Third, cook the salmon skin-side down. This will help to keep the salmon moist. Finally, baste the salmon with a little bit of butter or olive oil while it is cooking to help keep it moist.
