Living with her, and in other countries, also forced me to realize how weird and distanced American culture is toward meat. Growing up, I was sort of taught / sort of allowed to be grossed out by many cuts of meat. E.g. on a chicken, I'd be kind of horrified by the bits near the bones and focus on the rather anonymous bits like the breast, where you can almost pretend it's not meat. Organs, cartilage, tendon, etc were all utterly unthinkable. Even particularly dark pieces of meat (again, on chicken) were kind of just... avoided.
Not so much in other cultures. My wife gleefully eats just about any part of an animal. And as I've come around to trying things I've discovered that all those weird bits are wonderful. Even intestine, in the right preparation.
Which presents a quandary. What if we split up and I wanted to try being vegetarian, with fake meat / meat substitutes? Well, those fakes are decent at replacing something like chicken breast, or a piece of sausage. But I can't imagine that anyone is rushing to find an alternative to fried cartilage, or sliced liver, or marrow in the bone, or stewed tendon. And I'd miss the hell out of those things, now that I've learned to enjoy them.
