Be sure to sift the flour, boil water, and grate the cheese on a medium grater.
In a small bowl, combine milk, hot water and salt, stir ingredients. Pour the previously sifted flour into the deep bowl in which you will knead the dough and pour in the prepared milk mixture. Knead the dough until it is elastic and pulls away from the sides of the pan. Wrap the finished dough in cling film and place in the refrigerator for about 30 minutes.
Prepare a work surface for forming chebureks by sprinkling the table with a small amount of flour. Remove the risen dough from the refrigerator and divide into several equal parts, rolling into balls. Take one ball of dough and roll it into a thin round layer, put the grated cheese filling on one half, cover the first half with the other half and press the edges with a fork. Follow similar steps with all dough and filling. Place the finished pasties on a board sprinkled with flour.
Pour vegetable oil into a frying pan with a thick bottom and set to heat. Place 2 chebureks in oil and fry on each side for a few minutes until golden brown. Place the finished pasties on a plate lined with paper towels to remove excess oil.
Serve the finished pasties hot, topped with sauce to taste.
