An Iron Chef must adapt to a secret ingredient that is revealed just moments before cooking. For their next test, host Alton Brown asks the remaining seven chefs endure a tough test of Adaptability. The chefs have 90 minutes to prepare a savory and sweet duo of Mexican-inspired dishes and a creative beverage that successfully utilizes a secret ingredient flown in from Mexico on American Airlines. At the iconic Grand Central Market, the chefs shop for additional indigenous ingredients to effectively capture the heart and soul of Mexican cooking. They are judged on how well they adapt the secret ingredient to their culinary creations. One chef is eliminated.
