Start by making your Marie Rose sauce. Mix together the ketchup, mayonnaise, Worcester sauce, brandy and lemon juice. Season with salt and pepper and a sprinkling of paprika and stir.
Slice up the lettuce and avocado and set aside. Mix the Atlantic peeled prawns through the sauce and begin to layer up in a cocktail glass.
Finish with a few whole tiger prawns around the glass and another sprinkling of paprika.
