Nigella shares her go-to celebratory cake - a divine, layered chocolate and peanut butter cake that will make even die-hard haters of peanut butter relent.

As winter draws in and the nights get cold, Nigella creates recipes that deliver comfort and warmth to banish the winter blues. Nigella's grandmother's recipe for creme caramel provides the inspiration for a simple but elegant dessert of caramel custard.

Nigella then rifles through her pasta collection to find the ideal pasta shape to go with her spicy sauce made from Italian 'nduja and cavolo nero. This is followed by a visit to the famous gadget cupboard for an electric potato masher to prep her brown butter colcannon, the perfect match to a dish of black pudding meatballs in tomato sauce.
