Barm cake

A barm cake is a soft, round, flattish bread item from North West England, traditionally leavened with barm. Bacon is often the filling for a barm cake, at home or in Lancashire cafes or bakers. Chips are also a popular filling, sold in most fish and chip shops in the North West of England and often called a chip barm. Another popular filling in the North West, particularly Bolton, is a pasty barm. In Wigan, a whole savoury pie is served in a barm cake, traditionally known locally as a “pie barm” or “slappy”. More recently it is known as a "Wigan kebab", including on the menu of the local football team Wigan Athletic.
