For chefs Aaron Sanchez and Roger Mooking, Heat Seekers is a tongue-testing odyssey to discover the most delicious and dangerous spicy food in the country - and figure out why it's so much fun to eat. In each city, they discover the secrets of everything from Mexican to Korean to Indian cuisine then subject themselves to a test of who can handle the heat. What results are either tears of laughter or tears of pain... Usually, it's both.
