Black Soy Bean Drink

All right, for this breverage, you will need both the electric lunchbox and a blender.

The steps are super easy. To one cup (rice cup) of black beans, add 600 ml of water. Let it cook in the electric lunchbox for about 2 hours so that the beans will be soft. Next, pour the mixture to a blender and blend it. And you will have black bean soy drink. Add sugar as required.

Enjoy!
