This delicious panettone and brandy butter pudding is the ideal solution for those Christmas leftovers we all have lying around at the end of December. Panettone and brandy butter are layered up with a custard made from eggs, sugar and cream, made even tastier with a generous glug of Cointreau or Grand Marnier. If you don’t have the right size dish, you can also make two smaller puds – see the Variation tip below.
