Margarine grate on a coarse grater, mix with flour (approx. about 4 cups), RUB palms, salt (optional). In a glass of kefir teaspoon soda and stir thoroughly, for the reaction, and the yogurt boil. Pour the yogurt into the flour, add the egg and grated cheese on a coarse grater. Knead the dough, if the flour - add. The dough should be soft like plasticine. As the kneading, leave for 10 minutes to rest. Then again remember, it will be soft and manageable. PS: if you want, into the dough add a little salt. In the recipe, actually salt is not provided, as itself that the cheese is so salty, but again, depends on the cheese. I still suggest a little salt.

Divide the dough into 10 pieces. Roll into balls and in the center of each "ball" to put a piece of butter.

Desipite edge, again roll into balls and form rolls.

Rolls put on a baking sheet, greased and covered with parchment, seam side down.

Grease muffin with egg yolk.

Sprinkle with sesame seeds and send in preheated oven to 190 gr. 30-35 minutes, until, until browned. Well rolls both cold and hot ( my husband always heats them in the microwave, so he likes)
