Sugar and macerate at room temperature butter is mixed well. Add egg yolk, vanilla and salt. Gradually add the flour and mix a ball, which was allowed to stand for at least 1 hour in the refrigerator. Roll out thin crust (about 3 mm), from which are cut rectangular walls of the box. I use as a template box of tea. So cut rectangles are arranged on a tray covered with baking paper. With straw juice drill holes in the four corners of each rectangle. One of the rectangles provided to cover drill only 2 places on the long side. Bake about 8 minutes (monitored) to pinking in a preheated 180 C oven. They are sufficiently cooled down, the walls of the box are removed from the baking paper and connect with satin ribbon. Decoration: kisses crushed and sifted through a sieve. Add slowly juice until a thick homogeneous mixture. It partially smeared walls and lid of the box.
