Soak lentils in lots of water overnight.
In the morning drain water and wash by draining and adding water 2-3 times. Do not rub. Finally drain all water.
Cover and keep in warm dark place.
At night add water and drain out.
Cover and keep again as before.
By morning 3/4 long sprouts are ready!
Preferably use a porous container eg. an earthen pot. for best results.
