Squirrel counts as vermin, not game, so it wouldn't count as poaching, I don't think.
I still eat faggots, black pudding, liver and steak & kidney on occasion. Never really liked tongue, but we always had one at Christmas because Dad loved it - boiled, outer skin removed, then pressed in a tin. I met up with a former housemate earlier this week, from when we shared in the mid-'90s and she said she always remembered me making rabbit stew. That was probably the last time I did make rabbit stew because I haven't been given rabbit since around then, and I don't know of a game butcher round here (not that I've looked - I'm sure one of the villages would have one, even if then doesn't.)
We never had tripe, because Mum hated it, but I remember having brawn (and not being delighted by it,) and we probably had sweetbreads, but don't remember them. Definitely had pheasant, often, which I don't like too well hung.
Sugar sandwiches weren't a thing in our house, but I remember we went to a college friend of Dad's, who was a bulb farmer in Norfolk and they had coloured sugar sprinkles from one of his work trips to NL - they insisted we try them on buttered bread. I felt ill after. But i didn't like syrup sandwiches, nor honeycomb on bread, which Mum loved. I never added sugar to cereal or fruit, either (yet I'm the one who's ended up with type 2 diabetes...)
