Remoulade

Rémoulade is a cold sauce. Although similar to tartar sauce, it is often more yellowish, sometimes flavored with curry, and often contains chopped pickles or piccalilli. It can also contain horseradish, paprika, anchovies, capers and a host of other items. It is often used as a condiment or dipping sauce, primarily for sole, plaice, and seafood cakes (such as crab or salmon cakes) but also served with meats. Rémoulade is originally from France, but can now be found throughout Europe and in the United States, specifically in Louisiana Creole cuisine. It is often used with French fries, on top of roast beef items, and as a hot dog condiment, although there are many other applications around the world.
