This week's quickfire challenge consists of our cheftestants inventing their own gourmet hamburger. They have 1/2 hour in which to accomplish this task. The judge, celebrity chef Daniel Boulud, created the DB Burger, or a ground sirloin with a filling of boned short ribs braised in red wine, foie gras, black truffle and a mirepoix of root vegetables. The homemade bun is topped with toasted parmesan and layered with fresh horseradish mayonnaise, tomato confit, fresh tomato and frisée lettuce.CJ won the quickfire with a scallop mouse and shrimp burger, which Daniel Boulud described as "beautiful."
