Prepare black beans, black rice, black sesame seeds, walnuts and other materials in a ratio of 3:2:1:1, and also prepare an appropriate amount of rock sugar.

1. Wash the black beans, black rice, and black sesame seeds with clean water. Use the filter of the soymilk machine to wash the sesame seeds without leaking out at all, which is more convenient.

2. Put black beans, black rice, and black sesame seeds into the soymilk maker, and add water to the lowest water level. If you want a thinner drink, add water to the highest water level.

3. Press the double-thick grain button of the soymilk machine. It will be completed in about half an hour. After pouring, add rock sugar, stir and melt, and then drink.
