Just before making the dosas, add remaining 2 tbsp of rava and 1 cup water to the batter. Mix well.
Meanwhile heat the iron or cast iron pan for making dosa. Once hot, set it on medium heat. Drizzle few drops oil and Sprinkle few finely chopped onions on the tawa.
Mix the batter thoroughly and take a small glass for bowl of the rava dosa batter.
Pour it from a height starting from the circumference (edge) of the pan towards the centre in circular motion, filling any large gaps. This has to be done quickly and do not pour lot of batter at one place…It should be lacy & porous.
Drizzle oil all over the dosa, filling all the holes.
Cook the dosa on low to medium heat until the bottom looks golden brown & the dosa leaves the sides of the pan. It takes about 8 to 12 minutes.
Gently lift the dosa from the edges and fold it in half. Remove from heat. Do not flip.
As you make dosas, the batter thickens. So, add extra water to the batter to maintain consistency and mix it well before making each dosa.
Repeat the same process for rest of the batter to make rava dosa.
Serve hot with any chutney of your choice!
