Put all the ingredients in a blender and grind until you get crumbs that can hold the shape. Roll into a ball and put in the refrigerator for 20 minutes. You can knead the dough with your hands. To do this, mix the flour with sugar and salt, add the butter and rub your hands into the crumbs. Then add the yolk, water and juice and quickly knead the dough. Then place the dough in a thin layer on the bottom and sides of the mold. Put it in the freezer for 10 minutes. Then prick with a fork all over the bottom and bake for 15 minutes.
