"Most cooks can make a good burger. But it takes a real pro to make a great burger with a surprise ingredient of breakfast cereal," host Geoffrey Zakarian told the contestants. According to judge Graham Elliot: "I think what the pro's going to do is use that cereal for texture, something to give it some crunch. If they put it in the actual patty, pate mix, I think that's a clear indication of amateur." For will-be con Jimmy, the cereal served as a coating for his onion rings — and he ended up winning the round.
