With spice grinder in hand, Gustav Brunn traveled to America from Germany, and settled down in Baltimore on the Chesapeake Bay, where steamed crabs are a staple. Gustav began grinding. In 1939, after trying many different combinations, Gustav found just the right mix for a top secret blend of spices that would be the most-used seasoning on steamed crabs, shrimp, lobster, and other tasty seafood dishes for generations to come. But McCormick & Co., which purchased Old Bay in 1990, insists that the celery salt based blend is not just for seafood. You can also use the seasoning on chicken, French fries, popcorn, baked potatoes, deviled eggs, hamburgers, and even pizza.
