Make sure to buy farmed scallops or diver-caught scallops to ensure that they are sustainable. Frozen is better always. Bay scallops are sweeter, creamy and more tender.
When shopping for scallops, look for “dry” scallops. These have been shucked and shipped packed on ice, with no chemical additives.Wet scallops have been treated with water and chemicals to increase their weight and shelf-life. They have been soaked in a solution containing phosphate, a whitening agent that keeps them fresh longer but also allows them to soak up more water, increasing their weight by almost 30 percent Dry packed scallops do not contain any additives and will exude very little water. Because of this, they are the preferred choice for chefs.
