Bread and butter pudding. Spread slices of leftover bread (maybe you have a Christmas panetone lying around?) with butter and the marmalade, and arrange in the shallow baking tin. Whisk together 3 eggs, just over a cup of milk or half and half, 2 Tablespoons of sugar and a drop of vanilla. Pour over the bread. Plan the tin in a larger baking tray and half fill with hot water. Bake in a moderate oven for about 35 minutes. Yum!
