The last time I had salad cream was at junior school. I never touched another salad until I was 32, it was that bad. I don`t like mayo on a salad either although I like to use the reduced fat version to make creamy mashed potato.
So a few salad cream lovers like me. Never been a fan of mayo, it seems a bit boring and pointless, salad cream has a shaeper taste and makes a salald/pasta bowl a bit more exciting imo.
