I love hare, but I don't shoot anywhere where they're around and have never shot one. I had a good chance at one on a driven shoot a couple of years ago, but there was a no ground game rule. I had a shot at one ten years ago on a trip to Scotland. It accelerated past me like a cheetah and I missed it about two metres behind!
I've never made croquettes out of them, sounds interesting, although I daresay you'd end up with a hell of a lot of them, there's a lot of meat on a hare. I've kept a hare recipe from "Le Chasseur Francais" last month called "Lievre a la Royale", as it is the most insanely elaborate recipe for anything I have ever seen. It takes three days, and the first step is to bone the hare in one piece taking care not to pierce the skin, which isn't butchery, it's microsurgery! I should scan it and post it on here.
