Don't forget that until 1954, when meat came off the ration, the only thing available was offal, if you had used all your coupons, which wasn't rationed. Perhaps by that time it had become an acquired taste for some.
One of my earliest childhood memories is of sitting on my Gran's knee at the tea table with her spooning tripe into my mouth and me immediately spitting it out again.
She did not persist and I have never tried tripe again, nor do I ever intend to.
My Dad used to love it, Mum couldn't eat it.
Bad luck for him, good for me!
When my grandad lived with us when I was a teenager, my mum regularly cooked tripe and onions for him. I only ever tried one tiny piece and wondered how he managed to finish a plateful of the stuff. Vile.
