Square Loaf

A loaf specially designed for making ‘pieces’ (sandwiches) that fit into a square lunch box. It is also known as a ‘plain’ loaf (distinguished from a ‘pan’ loaf which used to be considered a posher version, since it was made in a tin, and became a slang term for those who had aspirations above their station), or ‘batch bread’ in a system of baking bread where the loaves are tightly packed on a tray and rise upwards rather than outwards giving them their tall shape. It is the half slice which is square.
