Trade Up or Die Tryin'

It's the penultimate leg of Chef Race and only four chefs remain - two Brits and two Americans. Starting in Bedford, Pennsylvania, with nothing but a sack of potatoes each, the teams are charged with "trading up" to acquire other ingredients for a cookoff at a trendy Baltimore, Maryland restaurant. The grand finale - New York City - and the $100,000 prize is literally just around the corner!
