The Michelin-starred chef met the housemates in the garden, where he demonstrated how to make one of his signature dishes - sea bass with chinoise sauce. The celebrities will have to recreate the dish from memory in just 30 minutes.
The housemates have formed pairs and will compete against one another in the specially built kitchen in the large task room to be crowned Big Brother's Best Chefs.
Paddy Doherty has paired with Kerry Katona and Bobby Sabel with Amy Childs, while Tara Reid and Lucien Laviscount are working together. Darryn Lyons and Pamela Bach Hasselhoff have teamed up, leaving Jedward to form the final pair.
The winners will be rewarded with a lavish private dinner for two this evening, while the pair deemed the worst chefs by White will have to wash up everyone else's dishes.
Last night, Sally Bercow became the first person to be evicted from the Celebrity Big Brother house.
