*What is the difference between sea and bay scallops?
Guiliano Hazan points out that in his mother's version of the recipe, she uses bay scallops but he prefers sea scallops. So what's the difference? The biggest difference is size—sea scallops are nearly 3 times larger. Sea scallops are also mostly farm-raised whereas bay scallops are only found in bays and harbors on the east coast. Sea scallops are the ones that you generally get in restaurants, seared or grilled. Bay scallops are smaller, more tender, sweeter and used in chowders, stews, and casseroles.
