Prepare the ingredients in a deep and medium bowl, whisk with a whisk and sift through a sieve. Open the kefir, pour 1 cup from the package and take it inside, put the rest of the package in the sink under a thin stream of warm water. Grate the sausage and cheese on a coarse grater, put them in a small bowl, cover with foil on top and put in the refrigerator. While you are grating cheese with sausage, kefir will become warm. Break the eggs, add a teaspoon of salt and a tablespoon of sugar (both without a slide), stir well, pour in the rest of the kefir pack, mix again. Put the resulting mixture through a sieve, add flour with baking powder. To start, pour 1 cup of flour, and then adjust the thickness of the dough after kneading. Gradually, when kneading, add more flour. I got another 2/3 cup. The dough should remain liquid. A trickle flows down from the corolla. Let the dough stand for five minutes, meanwhile put the pan to heat up on a small fire and choose which fat to fry. I prefer to fry in lard.
