Christmas pudding has its roots in medieval English sausages, when fat, spices and fruits (the best preservatives of their day) were mixed with meats, grains and vegetables and packed into animal stomachs and intestines so they would keep as long as possible. The first records of plum puddings date to the early 15th century, when “plum pottage,” a savory concoction heavy on the meat and root vegetables, was served at the start of a meal. Then as now, the “plum” in plum pudding was a generic term for any dried fruit—most commonly raisins and currants, with prunes and other dried, preserved or candied fruit added when available. By the end of the 16th century, dried fruit was more plentiful in England and plum pudding made the shift from savory to sweet. The development of the pudding cloth—a floured piece of fabric that could hold and preserve a pudding of any size—further freed the pudding from dependence on animal products (but not entirely: suet, the fat found around beef and mutton kidneys, has always been a key ingredient).
