When cooking fish, always follow the Ten Minute Rule—Measure fish at its thickest. Allow 10 minutes cooking time per inch of thickness. For fish measuring less than one inch, short cooking time proportionately. Avoid overcooking. Fish is ready when flesh flakes easily with a fork.
Dolphin, the fish not the mammal, has a firm white meat of solid flake when cooked and a delicate flavor. Dolphin fish are easily caught in Florida and other gulf states and are best served simply cooked, whether baked at 350, broiled, grilled, or sauteed, just follow the 10 minute rule.
