Lancashire butter pie

Lancashire butter pie consists of shortcrust pastry filled with onions, potatoes, butter, salt, and pepper. Although vegetarians might think that this pie is suitable for them, they need to be apprehensive because bakers sometimes use lard in the crust. The pie is derived from local meat-and-potato pies, but the meat is replaced with butter because a sizeable Catholic population in Lancashire couldn't consume meat on Fridays. Therefore, this pie has got alternative names such as Catholic pie and Friday pie. These days, butter pie can be found in supermarkets and local chippies, and it is traditionally served with pickled red cabbage on the side.
