Adai & its variations.

Adai is made of rice & dals. The combination dals can vary as per one's liking, & each combination will have its own taste !
Rice 2 cups   chana dal 1 cup     udad dal 1/4 cup
arhar dal( tuvaram paruppu) 1 cup   methi seeds 2 tsp
red chilies 3           green chilies 3-4 or you may use only green chilies as per your taste, as it has Vit. C  & salt to taste, about 1 1/2 tsp.
soak rice & dals together for about 3 hours & grind it coarsely along with chilies & salt. let it ferment till eve/ over night. In a thick tava, heat it well, smear some oil & put ladly full of this batter, spread it, put about 1 tsp of oil all over it, cook it in slow flame, turn & cook well on both sides till it gets golden like in the picture on the left. 
For onion lovers, you may add some finely cut onion & mix it with the batter or put it on top of each adai & make it in the same way. 
Coconut lovers may add some grated coconut in the batter & make in the same way.
This goes well with Milagai podi/ gun powder, those with sweet tooth may love it with gur/ jaggery/ vellam  & butter.

Or the batter can be made with rice, not basmati, normal parmal/ boiled rice will do 2 cups, you may use black udad dal  11/2 cups, chana dal 1 cup, arhar dal 1/2 cup along with chilies to taste, soak & grind in the same way. Only thing when using black udad, you may need to soak a bit longer. The coarser you grind, it will come out crisp & better. This is a good snack. it is rich in carbohydrates, proteins too, when eaten with sambar which has veges in it, it makes a complete meal. You may add some finely cut curry leaves a big handful to the batter, as it tastes good, or finely cut drum stick leaves, as these are rich in iron & calcium also in the batter & make adai as usual.

ps- those who are diabetics, you may use less of rice, or use dalia instead of rice, wash & grind it last with dals. You can use green moong dal also, those who aren't allergic to peanuts may grind it with dal last. There is no hard & fast rule to the combination of dals one wants to use!
You can see the picture of the batter below.
