Buttery, light and utterly delicious, shortbread is one of Scotland’s best-loved biscuits, and it’s largely thanks to Mary, Queen of Scots for popularising the teatime treat during the 16th century. It’s believed the royal loved petticoat tails, a classic triangular style of shortbread speckled with caraway seeds. Our shortbread recipe, however, is a simple bake using just unsalted butter, salt, caster sugar, plain flour and cornflour – and the result is mouthwateringly good. Enjoy the biscuits on their own, or whip up an easy roasted plum accompaniment and serve with crème fraîche.
