I'm hoping someone can help me...
From 1961 to 1967 I attended Tilney St Lawrence primary school in West Norfolk. The school cook was Mrs Griib.
Our school lunch menu - which I enjoyed immensely, by the way - included a weekly salad, which was always accompanied by Mrs Griib's own "salad cream"... only it wasn't remotely like Heinz's familiar version.
It was white and had a strong, distinctive smell and a very sharp taste, which I found delicious. She made it in a great bowl and you got a large spoonful on the side of your plate.
I have never tasted anything like it, before or since, and I would dearly love to know how to recreate it.
Sorry if I'm repeating myself, I stress that it wasn't anything like salad cream or mayonnaise or any other dressing I've tasted since. It was something altogether different.
I don't know whether it was Mrs Griib's personal recipe or whether Norfolk's education authority issued this recipe for salad dressing? I doubt if it was the latter, though, because when I went up to the local Grammar School in 1967 they dished up ordinary (but watered down) salad cream (like runny Heinz).
Maybe there's a fellow ex-Tilney pupil on here who can recall it and, better still, share their on how to make it! I'd be very grateful if you could...
