Chefs Aarón Sanchez and Roger Mooking aren't afraid of a little spice in their food. In fact, they seek it out. The duo hits the road on an odyssey looking for some of the most-delicious, spicy food in the country, and they then try to figure out why the dishes are so fun to eat. After discovering the secrets of spicy dishes of various cuisines, including Mexican, Korean and Indian, Sanchez and Mooking subject themselves to a test of who can handle the heat. Tears of laughter or tears of pain -- or both -- often result from the taste tests.
