Knead a shortcrust pastry from all the ingredients (except the almonds) and cool it for approx. 2 hours. Shape the dough into fingers and press an almond onto the tip as a nail.
Mix an egg yolk with a little coffee and brush your fingers with it. Press in the finger folds with a knife. Bake at 180 ° for approx. 15 - 20 minutes until golden brown.
