A fish that is a member of the porgy family, which is only found in the Atlantic Ocean. Its profile and teeth structure resemble that of a sheep. The flesh of this porgy has a firm, flaky texture with a sweet flavor. The sheepshead porgy is no relation to the sheepshead found in the Pacific Ocean or the freshwater drum, which is known as sheepshead. Tilefish or black drum can be used as a substitute for sheepshead porgy. To check the fish for doneness, use the tip of a sharp knife and cut through the thickest part of the fillet. If the fish has been properly cooked, the meat will appear opaque but will still be moist.
