The traditional Prawn Cocktail goes in and out of fashion as an English starter. It was very popular in the 1970s and most restaurants would have a version of this popular starter on their menu. Over the years since the good old Prawn Cocktail has been de-constructed by various chefs and then re-constructed back to its original concept. It seems whatever happens, the Prawn Cocktail remains a firm favourite.
Traditionally a Prawn Cocktail should be served with brown bread and butter, so for those members of your family who are not low-carbing should certainly be offered this option; however homemade prawn cocktail is so yummy that I do not really miss the bread and butter.
You could make this and accompany with a salad for a nice tasty low carb lunch.
Prawns can be fresh or frozen, but you should ensure they are not too small and they are dried out thoroughly so the Marie Rose Sauce is not watered down by prawn juices.
