I like beef and calf meat. I love deer, when it is female or young, hard to take the big boys though - they stink. I think I had a Romney lamb, and it was more pleasant. I liked goat cooked.
I do see some progress toward a more primal palette. I just ate a fair amount of 2 week old pig liver. It was open to air in the fridge. It kept very well. The membrane around the liver turned into a dark skin, but I peeled it back and it smelled very good. I'm happy when I notice these little "improvements" in my appetite, but they are slow.
Have you/or anybody eaten raw squirrel or rabbit? How did that go. I had a bad experience with my squirrel. Part of it is the grain feed meat, but my head is the other problem. When I butcher something I'm freaked by the messiness of it. I'm not much of a butcher; fur, feathers, guts all over. It's not food it is SOOO dead animal. My head is accustomed to skipping that step by going to the grocery store, even the farm, and buying in an appealing package. All other predators eat with just their claws and teeth, fur, guts, etc, only encourages them. I started to eat with my hands and tear meat apart, and bite into a chunk instead of cutting it. It feels right deep inside, but so foreign at the same time. I had this idea that I would rip open a squirrel and it will be clean and smell like the meat dept. That wasn't reality. The meat was fairly mild, but I couldn't get the smells that came from the butchering experience out of my head. Does this get better? I've butchered at least 20 times now, I still find it very unappetizing.
