Wash the soybeans with water a few times, pour off the water, take half of it into the juicer, then pour in water and press the button to squeeze it into juice.

Pour the squeezed juice into a sieve lined with gauze, filter out the dregs of the beans, since the flow almost can be squeezed by hand to dry the water.

Open fire on the pot, put the rock sugar, after the water boils, adjust the small fire to cook.
