Roasted Salmon with Butter
How-To Tips: Roast Salmon
Heat the Sheet
Watch the butter in the oven: It will bubble for a few seconds, but when the foam subsides, carefully remove the sheet. Tip it to coat the bottom, then add the salmon.
Checking the Fish
Insert a paring knife between the layers of flesh to check for doneness: Salmon is dark pink or orange inside when raw, even though the outside might be opaque.
Knowing It's Done
Perfectly cooked salmon separates into big, soft flakes and has some bright pink in the center. It will continue to cook a little more out of the oven.
