4. ABC Mania

Guy Fieri lays out what may be the hardest challenge in Flavortown history: Three chefs can only use 26 ingredients -- one for each letter of the alphabet -- over the course of two rounds. In round one, the chefs must make a chicken dinner using 13 ingredients, each one starting with a different letter from A to M. Then, round two has the remaining two chefs create their go-to seafood dish using 13 ingredients starting with letters N to Z. The chef with the highest score after this one-of-a-kind culinary spelling bee will get a shot at winning $20,000
