My grandma loved prawns, especially just bought ones from Brixton Market - which she'd peel, and eat a couple for luck. She made a fantastic prawn cocktail, and I've only just remembered her secret - Marie Rose Sauce.
Essentially, its 4tbs of mayonnaise, 1tbs of ketchup, dash of Worcestershire saure and a little lemon juice. Can't wait to make it. Of course I'll be using my vegetatian Worcerstershire sauce, with my um, fresh local prawns, which will of course be real.
Perfect starter for Christmas day, followed by stuffing and the works.
