A cold mayonnaise-based sauce that originated in France, rémoulade is a traditional condiment for crab cakes in New Orleans. You can assemble this version, a quick blend of pantry items, at the last minute or a few hours ahead. Its vivid color and zesty flavor make it the best choice for accompanying delicate chilled foods such as poached chicken, white fish, and, of course, crab cakes.
