A Christmas pudding is a traditional British dessert that is often served during the Christmas season. It is made from dried fruits, spices, and suet, which is a type of hard fat derived from beef or mutton. The ingredients are mixed together and then steamed or boiled in a basin for several hours. The pudding can be served with brandy or rum butter, custard, or cream. It is a rich and indulgent dessert that is perfect for a festive occasion.
