My favorite dog is simple: grilled dog, chili, mustard, raw onion on a grilled bun. I spent about a year trying to nail a recipe for coney style chili. Finally settled on sirloin, onions, some special chili powder, half pint of guiness and some beef broth. The key is to sweat the onions then add the meat and the broth at the same time. The meat poaches and the sirloin crumbles perfectly.
