There are a few rules to remember when you’re making scallops. 1: you want to purchase them with the side muscle is still intact and remove it from each scallop. 2: You don’t want to overcook scallops, that means high heat for 2-3 minutes per side TOPS! and 3: don’t futz with scallop and flip multiple times. You want them to have a nice crust on each side so let them cook, get that sear, and then flip.
