Salad cream is simply vile.
I agree.
We grew up pretty poor, but there was always salad cream in the cupboard
I think a big part of my aversion to it is because of memories of growing up in poverty. We did’t have it, but many other families did, and friends’ mums would make us sarnies with salad cream in. Being brought up not to be rude about food I was given, and to always be grateful, I’d eat them even though I was trying not to gag. And I’d always say thank you afterwards. Which just meant that the mums thought I liked them. So I’d get them the next time I went round, and so on. I learned to avoid certain houses around meal times.
There was a whole plethora of nasty foodstuffs when I was a kid. Another hatred is Spam; truly horrible stuff. With the Spam fritter being the ultimate in nastiness; how can you make something already horrible even worse? Deep fry it in greasy batter. Ugh.
Piccalilli though; I’d eat that out of the jar if left unsupervised.
