I do like various bits of offal like lambs and pigs liver and lambs and ox kidney (pigs kidneys always seem a bit bitter to me) and when I was a young boy my mum used to take me to a tripe shop at Derby Market. The tripe shop always smelt strongly of vinegar and we used to eat it raw as well as cooked. I don't think I was told what tripe was at the time but did enjoy eating it. We also had it cooked in milk and the taste was quite different. My Auntie Barbara remembers the tripe shop too and they used to ask for the honeycomb bit of the tripe. Tripe and onions (pickled onions) were a favourite with her side of the family when growing up and her Dad (another grandad) used to enjoy eating chitterlings (cooked intestines) and called them by a name I'd never heard before, hodge. This I gleaned from a short chat with Barbara on the dog and bone (phone) this morning. Speaking of dogs, her old dog in the 1960s used to be given a sheep's head with the brains exposed and, apparently, the Alsatian used to wolf these down. Imagine that now!!!! We had a laugh about walking into a supermarket and instead of seeing rows of canned dog food there would be rows of sheep's heads for sale! Macabre.
We also used to eat a lot of brawn where pig's cheek would have been shredded and cooked in the brawn mixture. My Grandad Lowe used to like to eat cooked sheep's brains as did a lot of his generation (folk born around 1890 and 1900) and he was particularly fond of boiled pigs trotters.
Cooked tongue was a regular part of my Sunday tea growing up and as part of my early days in the butcher's trade I was used to seeing ox and lambs tongues preserved in big buckets of brine as well as pigs intestines, also in brine, ready for cleaning and using for sausage skins. In fact I grew up seeing all the humane killing processes and gutted chickens and trimmed the meat off cows heads and lambs heads for cow's cheek and dog food. Even back in the 1970s people used to come into the butchers shops and ask for lites (the lungs of pigs of lambs and sheep mainly) to cook and feed their pets.
I'd try most things of this nature but grey chitterlings and their smell does turn my stomach a bit and as for sweetbreads and testicles, well call me fey but...
