Sprouts is the ultimate source of protein especially for vegetarians and vegans. Look here not only for step by step instructions to make sprouts in 36 hours but also as to why these should be eaten.
Soak them in water for at least 8 to 10 hours till gets double in size. Take enough water as they absorb a lot of it. If, in between, you find that water has been soaked fully then add more water. If the grains are not fully soaked then they do not germinate well. So, don't be in a hurry. Soak them well, better if overnight.
After 8 hours, put the lentils in a strainer and drain all the excess water. Use this water for watering your plants as it is high in nutrients.
Now take a big bowl. Once the water has been drained, transfer your soaked and drained sprouts in this bowl, cover with a plate and keep them in some warm and dark place. I prefer keeping this container in the microwave or Otg (of course, without running them). This is because grains require a warm and dark place to germinate and microwave provides it with the perfect environment.
Now, all you have to do is that twice a day, once in the night then in the morning, toss the grains and if completely dried out then make them wet by sprinkling little water. Cover with the plate and again back to their closed space. You need to make them wet because if too dry then even then they will not germinate. Do not put excess water else it may catch fungus. If you happen to add more water then put them in a strainer and remove excess water. Just keep them wet, that's it.
Once fully sprouted, transfer these in an airtight container and keep it in the refrigerator. Remains good for 4 to 5 days. Now, whenever you want, take little and use.
1/2 cup (100 g) green gram produces 2.5 cups (250 g) of sprouts in approximately 36 hours during summers.
