What Makes Mardi Gras Mustard Unique?
This Louisiana-style sauce stands out with its zesty, tangy flavor profile balanced by a mild spicy kick. The combination of creamy Creole mustard with horseradish creates a bold taste that’s distinctly different from standard yellow mustard or honey mustard.
The sauce brings authentic New Orleans flavor through traditional ingredients including bell peppers, celery, onion, and Cajun seasoning—the same aromatic base used in classic Louisiana cooking.
