Chop the butter with a knife into fine crumbs, separately dilute the yeast in a small amount of warm milk.
Now we will rub the butter with flour until smooth.
Add cottage cheese, yolk, yeast diluted in milk, salt and sour cream to this mass. Knead the dough.
The result was a ball. Leave it for proofing for 1 hour.
That's how the dough increased in volume.
Now we tear off small pieces from the dough and form balls, and then sticks (about 10 centimeters long). Put them on a baking sheet, (you can grease with yolk) sprinkle with cumin, coriander and bake at 180 degrees for 10-15 minutes.
These are cheese sticks. Try it with tea, coffee, soup or borscht.
