CROSTATTA

In a deep bowl, mix the butter with the flour, salt and sugar to get a sandy consistency. Add the yolk and cold water and mix. Wrap the dough in baking paper in the shape of a disc and leave it in the refrigerator to harden for about 40 minutes. Spread a crust with a rolling pin and set it in a round tin. Cut off the excess dough and put it back in the refrigerator for about 30 minutes. Preheat the oven to 170 degrees. Before putting it to bake, pierce it with a fork in several places so that it does not rise during baking. Bake for about 10 minutes at 170 degrees. Take out the hot dough and put the apricot jam mixed well on it. Top with the rest of the dough intertwined in a zigzag effect. Coat the crust with egg yolk and bake for another 15 minutes until golden brown. Cool the pie completely and serve cold.
