Concessionaires at the L.A. County Fair have been getting creative with their deep fried foods, serving everything up from deep fried frog legs to deep fried cupcakes. Bob checks his calorie counter at the gate to enter in the Fair's Deep Fry Contest - where fair goers judge each vendor's entry on originality, taste and appearance. Bob learns that deep frying is no easy feat - finding the right batter, the right combination of salty and sweet, and the right oil temperature to avoid a melted mess takes hours of trial and error. He hops in his vegetable oil fueled car to test out his deep fried experiments on his neighbors in L.A., with a pit stop to explore the art of tempura at a Japanese restaurant along the way. Will Bob's fried creation hold up on contest day, or will he be up to his elbows in grease?
