Liquid Crab Boil
When you're making giant pots of boiled shrimp or crawfish, you can always concoct your own special seasoning blend—or you can simply use ready-made seafood boil (often just called "crab boil" but sometimes by other variations on the name). It comes in liquid and powder forms, in sizes from a few ounces to economy-sized jugs. Think of it as Louisiana's answer to Old Bay.
