Padma and guest judge, Chris Cosentino divide the chefs into teams to compete in the notorious Top Chef mise en place race. In the elimination challenge, the same teams must go head-to-head and create a seven-course progressive meal with each dish featuring the same ingredient, the humble radish. They will battle it out course by course in front of a group of Top Chef superfans. Richard Blais joins Tom, Padma and Chris at the judges table. The team who wins the most courses will be safe while the losing team will be up for elimination.
