Soak 1/2 cup of mung beans in water for two to three days. Change the water every day.
Place the beans in a dish and cover with a moist paper towel for three more days. Sprinkle the sprouts every day with a little water and keep the towel moist.
Once the beans start sprouting, remove the moist towel. Lightly sprinkle with water on a daily basis, making sure to not over water, until the leaves grow.
This process should take about 10 to 15 days.
AS easy as that! If your sense of decoration is unique, you can definitely attract your guests in Norouz.
