I was surprised how many of these were things that were totally normal to me as a kid in the 80s, and so the idea of many of them doesn't personally disgust me. (When did chickens stop being supplied with giblets, anyway?) But even then my mum thought tripe was disgusting and unhealthy - and would buy tongue on the same occasion. Which seems odd now.
Medlars are to me something from Shakespeare and occasionally heard of in articles about fancy restaurants and thus a different type of thing totally.
