Epis is a fundamental seasoning base in Haitian cuisine, comprising a blend of fresh herbs, vegetables, and spices. This aromatic mixture is integral to the flavor profile of numerous Haitian dishes, serving as a marinade for meats, fish, and as a seasoning for rice, beans, soups, and stews.

The composition of epis can vary by household and region, but it typically includes ingredients such as parsley, garlic, scallions, bell peppers, onions, thyme, and Scotch bonnet peppers. These components are traditionally ground together using a mortar and pestle, though modern preparations often employ blenders or food processors to achieve a smooth paste.

The resulting blend is then combined with citrus juice, vinegar, and oil to enhance its preservative qualities and depth of flavor.
