An Iron Chef's ability to IMPROVISE is a key to success in Kitchen Stadium. When ingredients on the altar are revealed, combatants in Kitchen Stadium must respond quickly to what the Chairman has thrown at them. Guest comedian Kevin Nealon and the audience at the Improv comedy club in Hollywood throw ingredient suggestions at the chefs - everything from octopus to marshmallows, perhaps a coconut? Kevin selects a disparate list of ingredients to cook with and the chefs have 45 minutes to improvise an Iron Chef-worthy dish.
