Gumbo is often used as a metaphor for the mix of cultures that exist in southern Louisiana. The dish combines the culinary practices of French, Spanish, native tribes, and African slaves, as well as Italians and Germans. In the 18th and 19th centuries, people from these cultures lived together within a fairly small area with minimal mobility. This fostered an environment in which cultures could influence each other and meld to create new traditions and cuisine.
These settlers were primarily fishermen who soon began supplying large amounts of shrimp, crab, and oysters to the food markets in New Orleans. The Canary Islanders also brought “a love for well-seasoned food”, including use of ground cayenne pepper, a spicy hot red chili pepper."
