Shake well before using. Crawfish or Shrimp: Use 1 tbsp per 5 pounds of seafood. (5 fl oz per 50 pounds). Use enough water to cover seafood completely. Bring seasoned water to a rolling boil, then add seafood and return to boil. Boil 5 minutes, remove from heat and let soak 20 minutes. The longer seafood soaks the spicier it will be. Enjoy. Crabs: Use 1 tbsp boil and 5 tbsp salt per dozen crabs. Variations: For extra spicy flavor, add more boil to suit individual taste.
