Refrigerator Method - (Best Method) Remove scallops from plastic freezer bag. Place frozen scallops in a covered container in your refrigerator overnight. We like to place a dry tea towel under the scallops to soak up any moisture.   Cool Water Method – Place the frozen scallops in a large bowl and cover with cool water. Check on them in 15 minutes and replace with more cool water until thawed. Do not soak in warm or hot water as bacteria love this opportunity.   Do NOT use the microwave as this can make them tough.
