Boil the meat in salted water with bay leaf.
Mix flour and yeast, knead the dough and let stand a little.
In a separate container, mix the cheese with sour cream, add eggs, a pinch of salt and sugar. Mix the resulting mass well until smooth and carefully introduce the dough. Remove for 15 min. in a warm, dark place.
Grind the meat in a blender but not very hard and add to the finished dough. Divide the dough into 4 parts, roll sausages from each part, divide the sausage into several parts and make bagels from each part. Put on a board sprinkled with flour.
In hot oil, fry the chicken donuts under the lid on both sides, over medium heat, until golden brown. Pull out the finished donuts on paper towels.
