Sweet Pastry

• 350 g (12 oz, 3 cups) plain flour

Sift the flour on to a work surface and make a well in the centre. Put the butter, salt, sugar and lemon zest in the well and then add the egg. With your fingertips, gradually bring the flour into the centre until all the ingredients come together to form a soft dough. Knead very lightly for 1 minute, until completely smooth, then form the dough into a ball. Wrap in cling film and chill for 2 h
