liver paté

Good riddance to that, for how it's produced alone. Yes, I know you can get other than Goose pâté, but it's considered lower quality and inferior. The best pâté is fatty pâté, and there's only one way to make it and it's beyond cruel. Factory farming looks positively humane in comparison.

I think your point largely stands, with some regional exceptions. I mean, I live in the Midwest and most of the local grocery stores carry pig's feet, so people around here are doing something with then. But then, this area was settled largely by Germans, so you're going to find more of that than French pâtés or British steak & kidney pies.
