Pick and clean the mixed beans.
Rinse the beans for 3 to 4 times in clean water using a colander or strainer.
In a big bowl soak the beans with water covering 2 to 3 inches above the beans. Soak the beans overnight or for 8 to 9 hours.
Next day, discard all of water from the soaked beans. Rinse the beans with clean filtered water or water that has been boiled and cooled.
Place the beans in a clean and dry bowl. Cover with a lid (not too tight nor too loose) and keep them undisturbed for 1 to 3 days in a dry and clean place.
Check the next day to see if the sprouts are visible. If yes and you want a little longer sprouts, than cover with the lid again and keep undisturbed.
Do not toss or turn the sprouts. Just see and close the bowl with a lid.
Check the third day and if you are satisfied with the sprouts then do not keep the bowl again undisturbed. You can use the sprouted beans right away.
