Shortbread

Shortbread or shortie is a traditional Scottish biscuit usually made from one part white sugar, two parts butter, and three to four parts plain wheat flour. Shortbread does not contain any leavening, such as baking powder or baking soda. Shortbread is widely associated with Christmas and Hogmanay festivities in Scotland, and some Scottish brands are exported around the world. Shortbread originated in Scotland. Although it was prepared during much of the 12th century, and probably benefited from cultural exchange with French pastry chefs during the Auld Alliance between France and Scotland, the refinement of shortbread is popularly credited to Mary, Queen of Scots in the 16th century. Despite the enduring popular association, evidence for any connection between Mary and shortbread's origin is sparse. Triangular wedges of shortbread became known as "petticoat tails", and this form of shortbread has become particularly associated with Mary, Queen of Scots. It has been suggested that a French term for the wedges of shortbread was petits gâteaux or petites gatelles – little cakes, and this became "petticoat tails". It is now thought the Scots term derives from the decorated round edge of the segments which resemble petticoats.
