Just had an outstanding elk roast, prepared using an immersion cooker. The meat is sealed into a heavy-duty plastic bag (freezer bag is great) and then immersed in water. The immersion cooker clips to the side of the cooking container, and extends down into the water. It looks like a high-tech aquarium filter; it contains a heating element and also a circulating pump. You program the temperature and the time, and forget it. The cooker shuts off automatically, and more importantly it never exceeds the temperature required to give you the degree of doneness you desire. Before serving you must quickly sear the meat on a hot frying pan or grill to give it a nice browned exterior. The thing is super simple, virtually foolproof and actually fun to use; it's perfect for game meat. Even clean-up is effortless; once you removed the bagged meat, you are left with a pot of clean hot water, no grease or other crap to worry about.
I'm no chef, but I love this thing.
