Bay scallops are smaller than regular sea scallops. Because of their small size, they cook very quickly. Typically, cooking scallops is done by either pan searing, also known as sautéing, or by deep frying. Whichever method you choose, make sure that you have the rest of your meal already prepared.Also, Bay scallops are much smaller than sea scallops, averaging about 100 per pound. Sea scallops are around three times larger, averaging about 30 per pound. One obvious benefit is the short cooking time bay scallops need, plus they tend to be more tender and a bit sweeter.
