By reading the ingredients, I know it sounds absolutely vile. But I am telling you that it doesn't taste as bad as it sounds. I came across the experiment when I had no food in my house apart from a jar of mayonnaise, salt and vinegar crisps and bread.
Believe it or not but the taste of the mayo neutralises the tanginess of the salt and vinegar crisps. Together they balance each other out and the taste is quite nice. Go on, give it a go :)
