Overview: Four chefs return to Cutthroat Kitchen for more punishment and a second chance to outsmart and outcook their competition. Things start off with a blend when a chef gets to pulverize one competitor's hot dogs in a food processor. Then one chef goes back to science class when they're forced to cook pasta carbonara with a chemistry set. And finally it's anything but a day at the fair when a chef is handed a cotton candy machine to use as sugar for their brownies.
