Variations for crab boil seasoning sauce

Spicy crab boil sauce – Keep all the ingredients as they are, but add an extra ½ – 1 teaspoon of cayenne pepper.

Thick crab boil sauce – While the sauce is cooking down, try adding some more cornstarch to the crab boil sauce to make it thicker. I would start with ½ a tablespoon for every cup of liquid. You can also check out some other methods of thickening seafood boil sauces here.
