Simple and delicious cake with quince jam

For this cooking recipe, we separate the whites from the yolks. Then put the softened margarine, yolks, soda, 3 tablespoons of sugar in a deep bowl and beat with a mixer or a broom. Add flour and knead the steep dough. After that, we divide our dough into equal 4 parts. We put two of them in the refrigerator for 10-15 minutes. Whisk the proteins with 2 tablespoons of sugar with a mixer at high speed until a stable mass. The two parts of the dough that we did not put in the refrigerator, we roll out in a baking dish, it is necessary to make the sides (about 1cm) or as a basket. We put jam in this deepened space. We can choose jam to taste, I usually put quince or pear jam there. We take one part of the dough out of the refrigerator and rub it on a coarse grater on top. Spread the whipped whites, and rub the second dough, also on a coarse grater. Preheat the oven and bake for about 40 minutes. at a temperature of 180 degrees.
