My mum being a Yorkshire lass and a miner's daughter loved all the offal/insides of meat, so I've had a few brushes with some of the less appetising parts of animals. When she moved to Birmingham in the 1940s , I think she gave up on a lot of that stuff as she now considered herself as living 'down south'. In fact when I used to go and stay in Yorkshire during school holidays I was regarded as a "reet posh southerner" ! But I won them over with my penchant for flat cakes and oven bottom cakes (for those who don't know, these are breads not sweet cakes).
But I remember Mum still had the occasional tripe and onions (not for me thanks) and something called chitterlings. Never was sure what they were. Looked disgusting, so was never tempted.
I remember having a particular liking for soft roes, doubtless another thing which my mum particularly liked. Haven't seen those on sale for years.
