Panettone Bread and Butter Pudding

Bread and butter pudding has enjoyed something of a renaissance in recent times. In this recipe the bread element has diminished and been replaced with panettone, the light and delicious dome-shaped Italian yeast cake studded with candied orange and lemon peel and sultanas. Panettone is traditionally eaten at Christmas, but is available all year round from Italian delicatessens. It is difficult to cut when fresh, as it is so spongy; cut the panettone in half the day
