Farl
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 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). Modern commercially mass-produced potato farls, however, are often rectangular in form.
