A butter pie is a traditional English savoury pie consisting mainly of onions and potatoes. It is also sometimes served on a savoury barm cake. The pie is stocked by chip shops, sandwich shops, local corner shops and some supermarkets within Lancashire. It is also known as Catholic pie, Friday pie, air pie or a special.
Butter pies were served on match days at Deepdale, the stadium of Preston North End F.C. until 2007 when the providers, Ashworth Foods Ltd, ceased trading. With the new providers, Holland's Pies not offering a butter pie, two Preston North End fans started a campaign on Facebook calling for the return of butter pies to the matchday menu.[2][4] In 2010, the butter pie made a return to Preston North End's Deepdale stadium after the huge demand for the pie.[citation needed]
