Mongolian milk skin

Made of milk. When the fresh milk is poured into the basin, after 2-3 days, a thick layer of milk skin will form on the milk. Then take out the milk skin, sprinkle a layer of sugar on the milk skin, fold a milk skin on it, and finally cut it into small pieces and eat it in your mouth. It's delicious.
