A Christmas pudding is a traditional British dessert made from dried fruits, suet, and spices. It's typically served during the Christmas season, and it's believed to have originated from the 16th century. While the exact recipe may vary depending on the region, a Christmas pudding generally consists of raisins, currants, mixed peel, and grated apples, along with sugar, flour, and spices such as nutmeg, cinnamon, and cloves. The mixture is then steamed in a pudding basin for several hours until it's dense and moist.
