Angel Wings or Rose Cookies

Sift the flour, add the baking powder and baking soda. Then mix in the sour cream, egg yolks, and softened butter. Knead into a soft, pliable dough that doesn't stick to your hands. Wrap it up and let it rest for 30 minutes.

While the dough is resting, make the meringue. Whip the egg whites with sugar until stiff and glossy, holding their shape well.

Divide the dough into small portions, about 25g each. Roll each piece out very thin into a round circle.

Place a dollop of meringue in the center, carefully fold to shape into a 'rose' as shown in the video, and sprinkle with chopped nuts.
