cut tomatoes into big chunks and grind them without adding water into the fine paste.

blend the dosa batter, besan and the above tomato paste for 30 seconds to mix well. do not forget to add besan as it gives softness to the batter.

take the ground batter to a vessel.

add finely chopped onion, ginger, green chilli, coriander leaves and mix well.

add salt to taste.

heat a non-stick tava, sprinkle a little water on the tava and wipe it off gently using a tissue.

pour a ladleful of the batter on it and spread little bit in a circular motion.

add oil, if preferred.

close it with a lid and cook on medium flame.

the batter should look properly dried and it should turn golden brown.

then fry the dosa on the other side until it turns light brown.

serve immediately with coconut chutney.
