Whenever I cook scallops, they tend to shrink up quickly and burn on the outside. Even though I leave them in the pan for several minutes at a time, despite the shriveling and burning, they always end up raw in the middle. The insides are cold, fishy tasting, and, to be honest, pretty nauseating. What am I doing wrong? I usually saute them in a little oil on high heat, flipping them every so often when the side touching the pan starts to brown and stick. Scallops are my favorite food; please help!
