A bap is, at its simplest, a bread roll. At its more complicated, it is tender pillow of dough, often made with milk, lard, and butter. A more humble, Scottish version of the brioche. The bap is the ideal bread for a simple meat sandwich. Whether that meat is leftover boiled beef, mutton, bacon, or sausages, the bap takes a simple meat and elevates it to one of the most steadying sandwiches a person could crave. And it's especially good for those mornings when soaking up all of last night's bad decisions is a top priority.
