“Shopping for Shrimp” tells you how to buy shrimp based on environmental and human rights considerations. A less weighty consideration is fresh versus frozen. Unless you have access to freshly hauled shrimp, buying frozen shrimp, preferably individually quick frozen (IQF), is best. In fact, that “fresh” shrimp at most seafood counters likely was frozen and then simply defrosted for your convenience-often at an added price. When buying frozen shrimp, choose a bag without an excessive amount of ice crystals, then thaw as directed on the package.
