Episode 55 of "Futurama"
s04e11 30% Iron Chef

Bender attempts to become a chef, and is quickly rejected by the Planet Express crew. He then turns to the chef that inspired him, Elzar who also rejects him. Bender soon makes friends with some space hobos and, coincidently, one of them is Helmut Spragel, formerly the world's greatest chef. Helmut takes Bender under his wing and trains him to be a master chef by giving him a secret weapon—a crystal vile containing "the pure essence of flavor". A now confident Bender challenges Elzar to a competition in the televised kitchen coliseum known as the "Iron Cook" show.
