The chefs turn up the heat in this week's Quickfire to create a spicy, savory dish using some of the hottest peppers around. The chefs get a choice of one pepper to incorporate in their dish. The hotter the pepper the chef uses, the higher the value of prize money at stake if they win. In the elimination challenge, the chefs will be taking over the food court at the rodeo and taking part in their own competition -- a chili cook off! Guest judges Mary Sue Milliken and Susan Feniger from Top Chef Masters and Two Hot Tamales join Gail Simmons, head judge Tom Colicchio, and host Padma Lakshmi.
