Sweet Pastry Balls

Mix the wheat flour, butter, ricotta cheese, and salt until a uniform dough forms

Knead well to achieve a smooth consistency

Let rest for about an hour

Roll out the dough with a rolling pin and cut into circles using the rim of a large cup

Place a small amount of filling made with jam cubes in the center of each

Fold the remaining dough over the filling and press the edges together

Arrange the pastry balls on a greased baking sheet dust with breadcrumbs, brush with egg white mixed with softened butter, and bake in a moderate oven.
