You could grind it and make antelope stroganoff with sour cream, a touch of garlic, onions, mushrooms, etc. I have never cooked antelope but have cooked dry meats like emu and bison/buffalo. I have had good results grinding those meats and using them in creamy sauces, marinara, and chili. I like emu burgers and bison burgers, too. One could add fat when grinding, but I keep the meat lean.
Below is a link to a site with a meat nutrition comparison chart which includes fat content. Antelope is on the list.
