The junior chefs split up into pairs and must decorate as many doughnuts as they can in 10 minutes; Gordon's daughter teaches the chefs how to make her version of a hamburger and french fries; the chefs must replicate it to stay in the competition.

The celebrities get their first challenge, which is to cook a dish that they are famous for.

The grand finale arrives, with three final celebrities playing for the trophy, title and $100,000 for their charity; Martin Ben chooses the dish that will seal the celebrities' fate.

The judges explain today's challenge is increasing ingredients, decreasing time, with the six celebrities cooking having four pantries to choose from.

The judges decide to throw out the rules, wanting to see a dish that shows the culmination of everything the celebrities have learned in the competition so far; they have 90 minutes to cook whatever they want.
