A farl is any of various quadrant-shaped flatbreads and cakes, traditionally made by cutting a round into four pieces.
In Ulster, the term generally refers to soda bread (soda farls) and, less commonly, potato bread (potato farls), which are also ingredients of an Ulster fry.
It is made as farls (that is to say, flat rounds about 3/4 inch thick which are then cut into quarters).
In Scotland today, the word is used less than in Ulster, but a farl can be a quarter piece of a large flat scone, bannock, or oatcake.
[1][2] A farl is made by spreading the dough on a girdle or frying pan in a rough circular shape.
