Raw minced meat is meant for cat food. Though it tastes interesting when rolled inside something, not unlike how some sushi is made.
Anyway, I don't really care about the level of welldoneniness, as long as it's not dry or still bloody. I've also begun to like fried steaks of different varities (they fry everything here).
Regular steaks. Pork needs to be a bit on the medium+ side to taste the best. Beef needs to be above medium-, but not too dry, since the meat tastes like nothing without its juice. Chicken... just make sure it's moist and spiced well, it's really boring if not. Reindeer, elk (and other game) must not be cooked too much to be delicious.
With internal organs it depends. A big liver steak could be grilled quite well on one end of the steak, but be a bit juicy on the other end, to give it some variety, since liver is quite "boring" in big amounts. A skillfully prepared liver steak is one of the most delicious things I've ever eaten, though. Kidneys are trickier, as they can be ill-prepared in so many ways. I should get into learning it myself (the neighbours will thank me for the lovely odours). Heart is good when it's soaking in its own juices in the oven for quite a long time.
I mostly dislike fish foods, but will eat it if there is absolutely no other meat available. It has to be either smoked, cold-smoked or carefully grilled on the surface to taste like anything. A salmon swimming in its own grease and cream in the oven is also acceptable.
Salted raw salmon is excellent in small amounts, and I also have to mention vinegar-jarred atlantic herring with different spices (tomato is my favourite) is nice sparingly.
Just some preferences, but I really don't care that much. Eating good meat makes me happy.
Jam it back in, in the dark.
