Valentine's Sugar Cookies

225g plain flour
125g butter, softened
125g brown sugar
1 egg, beaten
Pinch of salt

Line a couple of baking trays and preheat your oven to 190ºC. Beat the butter and sugar together until fluffy. Beat in the egg, slowly.  Sift in the flour and salt. Mix well until it makes a firm dough. You may need to add a little bit more flour.  Sprinkle some flour on your work surface and a rolling pin. Roll out the dough until it is about 1/2 cm thick. Cut out your shapes and place on the baking tray. Gather up any leftover dough, roll it out again and cut out more shapes. Keep on going until all the dough is gone.  Bake for about 15 minutes, until light brown. Leave on a wire rack to cool completely before decorating.
