Mince pie is a staple Christmas snack in England, consisting of a crumbly pastry shell filled with dried fruits and spices (often called mincemeat). Originally, the pies contained both sweet and savory ingredients such as ground meat, lard, and cheese.
Due to their original, rectangular shape, people used to associate the pies with the manger Jesus had been laid in, and the snacks were prepared for Easter and Christmas, while the amount of spices and ingredients was used as a way to show off the cooks' wealth to other people.
