Charley26: from the reading I have done, Miracle Whip is very similar to Salad Dressing in the UK. Miracle Whip is thicker and comes in a jar like mayo does. It is sweeter and has more vinegar in it than mayo. Asda used to carry it, but I think they've stopped doing so. It can be ordered online if you truly want to try it. (I am strictly a mayo girl!)
