First take a large mixing bowl and add all the ingredients mentioned except for oil & water.
Mix it with your hands using a rubbing motion so that the ingredients like onion, curry leaves, etc get an opportunity to release their flavors
Add plenty of cups of water to make a thin batter ( I used about 4-5 Cups) and rest it for 20mins
After the batter rests for 20mins, it would have thickened a bit. Add more water ( I added about 1-2 Cups) to make the batter thinner, if needed
Heat a tawa/pan on hight heat. Once the pan is hot, apply oil. Rub it on evenly using a cut piece of onion.
Pour the batter onto the pan using a small bowl/mug. You dont have to do the circular motion needed for a traditional dosa, so please Refer to my video / pics below to see how to pour batter. We should ideally get a thin layer.
Let it cook for 30sec and drizzle oil on top. Continue to cook until golden brown and edges crisp up. Remove from pan.
Serve hot with sambar / coconut chutney / mint chutney / onion chutney / peanut chutney / tomato chutney / potato masala.
