(Please note: the butter should not be soft, nor too hard either!)
Quickly incorporate the egg into this sandy mixture
Put into a ball. Crush the dough with the palm of your hand several times to amalgamate everything
Cover with a film of flour and let stand in a cool place for about 30 minutes, covered with a cloth
Preheat the oven to 200 °
Place the dough on a floured surface and keep the flour close to you to flour the roll and your hands. Roll out the dough with a rolling pin 1/2 cm thick
Cut the dough into slices using a cookie cutter or a glass
Place the shortbread on a buttered baking sheet.
Bake about 10 minutes in a hot oven, watching the cooking: take out the shortbread when they have golden blond color.
