Mary Berry’s Plum Pudding is a traditional steamed pudding made with dried fruits, spices, suet (or butter), breadcrumbs, and a touch of brandy or rum. The mixture is packed tightly and steamed for several hours, which gives it a dense, moist texture. This dessert is usually prepared weeks in advance to allow the flavors to develop, and it’s often served with a rich sauce or custard.
Grease a 1.5-liter pudding basin with butter and set it aside. This will help prevent the pudding from sticking during steaming.
In a large mixing bowl, combine the plain flour, breadcrumbs, dark brown sugar, and suet (or grated butter). Add the currants, sultanas, raisins, grated apple, lemon zest, orange zest, mixed spice, and cinnamon. Stir to combine all the dry ingredients.
In a separate bowl, beat the eggs and stir in the brandy (or rum/stout) and lemon juice. Pour this mixture over the dry ingredients and mix thoroughly until everything is well combined.
Spoon the mixture into the greased pudding basin, pressing down lightly to ensure there are no air pockets. Cover the top with a layer of greaseproof paper and a layer of foil, pleated in the center to allow for expansion. Tie securely with string.
Place the pudding basin in a steamer or large pot filled with simmering water. The water should come halfway up the sides of the basin. Cover with a lid and steam for about 5-6 hours, checking occasionally to add more boiling water as needed.
After steaming, remove the pudding from the pot and let it cool completely. Once cool, replace the greaseproof paper and foil with fresh layers, then store in a cool, dark place. You can prepare this pudding up to several weeks in advance to allow the flavors to mature.
When ready to serve, steam the pudding again for 1-2 hours to warm it through. Turn out onto a plate and serve with brandy sauce, custard, or whipped cream.
