In a large mixing bowl, take ½ cup semolina, ½ cup rice flour, 1 tbsp curd, ¼ cup all-purpose flour/maida, chopped ginger, and mix it well.
Then add a little salt according to your taste, chopped coriander leaves, curry leaves, and 1 medium chopped onion and well again.
Now, add the water parts by parts till your batter is of flowing consistency. Mix all the ingredients very well.
Keep the batter aside to rest for 15 to 20 minutes.
After 20 minutes, the batter could have become a bit thick consistency. This is because the rava have soaked some amount of water.
Add some water again and bring it to the right consistency.
Take a non stick frying pan. Bring it to heat on medium flame. Apply some oil to the pan and let it heat.
As soon as the pan is hot, reduce the flame on low, mix the rava dosa batter again and add a ladle full of batter into the hot pan.
As the batter is watery, there will be big gaps in the dosa. Don’t fill the gaps with batter. Let it be as it is.
As soon as the dosa turns golden brown, remove it with the help of a spatula and serve hot.
