How to make
Beat the egg with the yolk, sugar and a pinch of salt. Add the oil, lemon peel and vanilla sugar.
Sift the flour and add it to the liquid mixture along with the baking powder. Knead a soft and smooth dough.
Sprinkle a work surface with flour and roll out the dough into a crust that is about 0.16″ (4 mm) thick. With a round shape, cut out small sweets, which are about 1.6″ (4 cm) in diameter. Arrange them on a tray lined with baking paper, by leaving some space between them.
Collect the cutouts and roll them out and cut them again - until you run out of dough. You will end up with about 4 baking trays.
Bake them in an oven heated to 360°F (180°C) for about 15 minutes - or until you see that the cookies aquire a golden brown color at the edges.
Leave them to cool, then stick the cookies together with jam or marmalade.
Easy and very tasty cookies, which will please children and adults.
