1

Rinse mung beans, place in a large bowl, and add enough water to soak for at least 6 hours until fully expanded.

Drain beans and grind in batches with some water using a blender into a fine paste. Strain through cheesecloth to remove pulp.

3

Pour the strained liquid into a container and let it ferment at room temperature for 24-48 hours until bubbly and sour-smelling.

Pour the fermented liquid into a pot, dilute with equal amount of water, and heat over medium flame stirring constantly to prevent sticking.
