Cheese and Sesame Rings (Susamli Çörek)

For 32 sesame rings

250 g margarine * 250 g lor cheese (or ricotta) without salt * 2 egg yolks * 4 1/2 cups flour * 1 tbsp baking powder

To garnish:

3 tbsp sesame seeds * 2 egg whites

Mix the margarine, the egg yolks, the crumbled cheese and the baking powder. Add the flour slowly and knead well. Separate the dough in four portions, cover with a cloth and let the dough rest for 20 minutes. Then open the dough, using a rolling pin, until you get the size of a normal meal plate. After opening, divide each portion into two. Open again each one but now divide each portion of dough in four. Roll each portion with your hands and connect the extremities giving the shape of rings. Brush each ring with egg whites and then sprinkle with sesame. Bake on a 175º preheated oven for 25-30 minutes, until they become light brown.
