Periwinkles (whelks), although as a child, I loved using a pin to pull them out of their shells for my maternal g’parents who both loved them. They just look like big dirty snotters to me.
Tripe, again my g’parents both loved it and often ate it, the smell was horrific to me.
Escargots, insects/grubs, sweetbreads.
And you’d have to pay me a huge amount of money to eat raw celery, anything coconutty, peanutty or sesame flavoured. My daughter loves dipping celery in peanut butter to eat, it smells like vomit to me ?
