Rinse the scallops in cool water then dry thoroughly with a paper towel.
Season the scallops with salt and pepper.
Heat a cast iron skillet over medium high heat.
Add butter to the skillet. Once the butter is melted and is starting to turn golden brown, add the scallops to the pan in a single layer, allowing a little space between each one.
Cook the scallops over medium high heat for approximately two to three minutes per side, until the outside, is seared and the internal temperature reaches 125°F.
