What sauce is used on the Crabby Paddy?

The correct sauce used on the Crabby Patty is Cajun remoulade. This sauce, originating from Louisiana cuisine, typically combines mayonnaise, various spices, and often some form of heat, such as hot sauce or peppers. This choice adds a distinctive zing and enhances the flavor profile of the Crabby Patty, marrying well with its seafood components and elevating the overall taste experience.

The other sauces, while flavorful, do not align with the Crabby Patty’s traditional topping. Garlic aioli is more aromatic and creamy, focusing on a garlic flavor which doesn't capture the essence of the dish. Spicy tartar sauce, typically associated with fried fish, offers a different taste profile that may not complement the Crabby Patty as effectively. Classic mayonnaise provides a simple creaminess but lacks the zest and complexity of flavor that Cajun remoulade contributes to this beloved dish.
