This griddle-baked unleavened flatbread hails from the Highlands of Scotland, where it is traditionally made with a single type of grain - whether barley, beremeal, oats, wheat, rye, or even peasemeal - with the addition of water or buttermilk.
Bannock made from a mixture of different flours is known as mashlum or meslin bannock. This flatbread was once an essential part of everyday life and various festivities in the Highlands, especially during the celebration of the quarter days, and each variety of bannock was given a different name depending on which of the old Gaelic seasonal festivals it was made for.
