Begin by placing the sultanas, currants, raisins and candied peel in a bowl.Pour over the brandy and leave aside to marinate. Then, in a large bowl, break the bread into ½ inch (1 cm) pieces. Add the milk, then give the mixture a good stir and leave it for about 30 minutes so the bread becomes well soaked. Pre-heat the oven to gas mark 4, 350°F (180°C). Next, mix the melted butter, sugar, mixed spice and beaten egg together and then add to the second bowl. Now, using a fork, beat the mixture well, making sure there are no lumps, then stir in the marinated fruits, with any brandy remaining, and also the orange and lemon zest.After that, spread the mixture in the baking dish and sprinkle the sugar over it, along with some freshly grated nutmeg. Bake on the centre shelf of the oven for about 1¼ hours. Meanwhile, whisk together the ingredients for the brandy cream and serve it with the pudding warm from the oven.
