In Kitchen Stadium, another Thanksgiving means another secret ingredient altar filled with a bounty of seasonal offerings. It also means another teaming of Iron Chefs Bobby Flay and Michael Symon, who continued to hold tight to their title as "Kings of the Thanksgiving Hill." The theme for this battle blended modern and historic Thanksgiving culinary traditions, and Chefs Flay and Symon took on two of the Chairman's finest, Iron Chefs Geoffrey Zakarian and Alex Guarnaschelli.
