Kamut tart with elderberry preserve

Pour the flour, diced butter, sugar and salt into a mixer, whisk, then add the yolk. Once a sandy consistency is obtained, transfer the dough to the work surface and form a dough to be covered with plastic wrap and put in the fridge for about an hour. After the necessary time, take the dough and roll it out with a rolling pin. Then spread the shortcrust pastry on the well buttered and floured bottom of a pie pan, leaving some dough for the edges. Spread the elderberry jam all over the base of the tart. Close the edges and bake in a preheated oven at 180 ° C for 40 minutes.
