Louisiana remoulade can vary from the French-African Creole, the rustic Afro-Caribbean Creole, or the Classic Cajun version, and like the local variants of roux, each version is different from the French original. Creole versions often have tan or pink hues and are usually piquant. Louisiana-style remoulades fall generally into one of two categories—those with a mayonnaise base and those with an oil base, but sometimes both mayonnaise and oil are used. Each version may have finely chopped vegetables, usually green onions and celery, and parsley; most are made with either Creole or stone-ground mustard. Salt, black pepper, and cayenne pepper are also standard ingredients. In the oil- and mayonnaise-based versions, the reddish hue often comes from the addition of a small amount of ketchup and/or paprika. The sauce is often topped with paprika for the aesthetics as well as the flavor. Generally, lemon juice or vinegar are added for acidity. Other additions include hardboiled egg or raw egg yolks, minced garlic, hot sauce, vinegar, horseradish, capers, cornichons, and Worcestershire sauce.
