Gently rinse and pat the scallops dry with a paper towel. Sprinkle with salt and pepper on both sides. Melt the butter over medium high heat. When the butter is melted, place the scallops into the pan, in a single layer. After 2-3 minutes, the bottom of the scallop should be nicely browned. Carefully turn all of the scallops over and cook for another 2-3 minutes. Remove from pan and place on a plate for serving. Keep in mind that you DO NOT want to overcook scallops. They will get very chewy. Removing them a little before they look completely done is fine too. They will continue to cook a little more after you remove them from the heat.
