"Seafood tip: Unless you live somewhere that you can get freshly-caught fish that's never been frozen, buy your shrimp in the frozen section of your store. Most seafood at the seafood counter has already been frozen and there's no way to tell how long it's been sitting in the case after being thawed. If you thaw your own you can control how long until it's cooked. Thaw shrimp in a colander while running cold water over it continuously until it's completely thawed...."
