* Most purchased scallops are wet-packed and have been soaked in a liquid solution that keeps them looking white. To remove this solution, rinse the scallops thoroughly and then pat them dry with paper towels. If you can find "dry-packed" scallops (which have not been soaked), you don't need to rinse them. Scallops have an adductor muscle (sometimes called a "foot") on it's side. It is s a tough little tab of meat that you should cut off before cooking the scallop because it can be kind of chewy.
