1. Soak black lentils and fenugreek seeds together in some water.
2. Soak both the rice together in another bowl.
3. After soaking them for 3-4 hours, grind the rice first in your wet grinder or processor.
4. The rice batter will still feel coarse when you touch it but otherwise it should have ground well.
5. Pour it out in a large bowl.
6. Next in the same processor/grinder (no need to clean it), add the black split lentil + seeds and grind it until fluffy and velvety smooth.
7. Now pour this batter, adding it along with rice batter.
8. Add this along with the rest of the batter.
9. Add salt and mix well until blended well.
10. Set aside to ferment overnight.
11. A successful fermentation is when you see the batter doubling up and you will get a sour smell wafting from the batter. There is something about sprouts which make fermentation a dream.
12. Mix it well once again.
13. Heat an iron skillet (low heat) or non stick skillet.
14. Add a little vegetable oil.
15. Cut half of an onion and rub the cut side down on the skillet.
16. It helps to avoid the batter from sticking to the skillet.
17. Once greased, drop a ladle of batter on the skillet.
18. Using the bottom of the ladle, in a circular motion, spread it around.
19. You can make it thick or thin.
20. The thicker crepes are soft while the thinner ones are for crisp.
21. Increase the heat and cook until you find that the ends of the crepes lifting slightly up.
22. Or if you try removing it, it comes easy from the skillet; turn it over.
23. It should be golden-reddish-brown in colour.
24. Grease it with onions again while starting the next crepe or simply drizzle some oil if dont want to use onion.
25. Fold it and serve these crepes hot and fresh with sambar or any chutney you like.
