An Iron Chef must be adaptable, so the Chairman’s Challenge offers up a combination of ingredients that will be bittersweet for one chef. All items are first-come, first-served and cannot be shared, so the competitors race to the altar to grab their most desired elements. Alton Brown sends the bottom chef to a sea creature-themed Secret Ingredient Challenge, along with the top competitor’s choice. Iron Chef Marc Forgione and Giada De Laurentiis judge the dishes and send one chef packing.
