Marie Rose sauce is a British dressing, made famous by the British TV chef Fanny Cradock in the 1960s when she served it alongside Prawn Cocktail. I haven't been able to find out where the name comes from, so we'll just have to settle for that. 😊
Marie Rose dressing consists of mayonnaise, sour cream, ketchup, Worcestershire sauce, a little lemon juice, and preferably a splash of brandy. The dressing is very similar to American Thousand Island dressing, but made without finely chopped pickles.
Marie Rose dressing is not only suitable for Prawn Cocktail but is also great to serve with crab meat and other seafood, such as salmon. The dressing also works well in a burger or as a dip for fries.
