When prepping scallops, there are a few steps you can follow to ensure they are clean, properly trimmed, and ready to cook: Purchase fresh scallops: Look for scallops that are firm, shiny, and have a slightly sweet aroma. Frozen is your next best option. Cleaning: Rinse the scallops under cold water to remove any grit or sand that may be on the surface. Pat them dry with paper towels. Removing the side muscle: Some scallops may have a small side muscle attached to them, which appears as a tough, rectangular flap on the side of the scallop. This muscle is edible but can be slightly chewy. I recommended removing it for a more tender texture. Simply pinch it between your thumb and forefinger and gently tug it away from the scallop. If it doesn't come off easily, you can use a small knife to cut it away.
