I've had heart a few ways. It's great fried in butter. I've also filleted it open, laid in a couple bacon slices, rolled it back up and baked it. Slice to serve. Pretty good that way too.
As for grinding a whole deer, I know guys do it, and it does make the meat easy to use, but you're really missing out on some of the best eating there is if you don't at least save the loins for steaks.
I just cooked a half loin in a cast iron pan with butter, salt and pepper. Cooked to an internal temp of 120, wrapped with foil. Needs to sit at least 30 minutes before slicing thin. If you'd rather eat ground meat than that, I'll never convince you.
