Where It Grows
Flounder is a type of flatfish that is primarily found in the northern Atlantic and Pacific Oceans. It is particularly common along the east coast of the United States, from Maine to Florida, and the west coast, from Alaska to California. These fish thrive in coastal waters and estuaries, preferring sandy or muddy sea bottoms. Flounder typically live near the ocean floor, and can even partially bury themselves in sediment for camouflage. Some flounder species are also found in the sea of Japan and China. Flounder fisheries are significant in the United States, Canada, Russia, China, and Japan.
Best Way to Eat
Flounder is a lean fish with a mild sweet taste and a delicate texture, which makes it versatile for a wide range of cooking methods. It is traditionally baked, grilled, or sautéed to maintain its nutritional value and enhance its natural flavor. To maximize the nutritional benefits, it is best to prepare flounder with healthy cooking oils like olive oil, and to pair it with vegetables or whole grains for a balanced meal. The fish is a great source of protein and is rich in vitamins B-12 and D, and minerals like selenium and iodine. To enhance the flavor, it can be seasoned with herbs and spices, like dill, parsley, or lemon zest. While it can be consumed with its skin, removing the skin can reduce potential exposure to environmental contaminants.
