Zatarain's liquid crab boil is a special blend of seasonings that gives you great tasting seafood every time without the guesswork. Zatarain's liquid crab boil is great for adding flavor excitement to other foods — hot dogs, fresh corn on the cob, potatoes, corned beef and ham. Just use the same proportions as for boiling shrimp. Or add a few drops in red beans, gumbo, gravy or marinades for extra zest. A New Orleans Tradition Since 1889
