Firstly, in a blender take 1 cup of Rava and blend into a fine powder.
transfer the powdered rava into a large bowl.
add 2 tbsp rice flour, 2 tbsp wheat flour, and mix well.
now add 2 tbsp hot oil and mix well well. adding hot oil to flour helps to get crispy dosa.

Further add 1 cup curd, 1 tsp sugar, ½ tsp salt, and mix well. adding curd helps to give sourness and activate baking soda.
add 1 cup water and mix using a whisk.
mix until a smooth lump-free batter is formed.
rest for 10 minutes helping rava to absorb water.

Now add ¼ tsp baking soda and mix gently.
pour the dosa over hot tawa and spread gently.
pour a tsp of oil and roast on medium flame until it turns golden brown.
scrape the dosa from the sides and fold half.
finally, instant dosa with sooji is ready to enjoy with garlic chutney.
