I decided to give sprouting a try and recently bought some organic mung beans, since I read that they were a good beginner-sprout. I used 1/3 cup of whole mung beans.
After washing them, I soaked them in water for eight hours.

I then placed them in a nylon mesh bag, which I tied up and allowed to drain into a bowl.
Over the course of the next couple of days, I rinsed the beans with water every eight hours.
They sprouted very quickly. I should have eaten them right away, because as they continued to develop, they grew more bitter.
They expanded so much as they sprouted - the initial 1/3 cup yielded a huge amount of sprouts.
