“Speedy” tart with plum jam

Sprinkle with flour a pastry board. In the center mix together the cold butter, sugar, eggs, a pinch of salt and 2 teaspoons of baking powder. Stir quickly until the dough has a compact consistency. Grease and flour the tray of the microwave or alternatively a normal baking tray, an ideal solution because heat is transmitted by conduction very well and this avoids the burning of the tart base. Spread ¾ of the dough, riddle with holes the surface using a fork and lay a layer of jam. With the dough left make rolls and place them on the tart creating a sort of a grate. Bake in the microwave for 12 minutes (“crisp” function) or in the oven at 180 °C for half an hour. Finally sprinkle with icing sugar.
