Only 11 cooks now remain. This time the challenge is all about comfort food, with dishes ranging from ginger and black pepper rice pudding to posh cheese on toast.

The cooks prepare some spiced sweet dishes for guest chef Yotam Ottolenghi, then serve up the spiciest spoonfuls they can muster to Nigella, Anthony and Ludo - with some eye-watering results.

The cooks keep it in the family, making recipes passed down through the generations. The guest chef Ruth Rogers sets the immunity challenge.
