Wash and soak rice for 2 hrs. Grate coconut and chop tomatoes.
First grind coconut, red chilies, and tomatoes to a fine paste. Then, add rice slowly and grind to a fine paste. Water can be adjusted based on the tomato puree.
The batter should be a little thin. Heat a tawa, apply cooking oil. Take a ladleful of batter and pour in a circular movement. This will not come out as the regular dosa, where you will pour the batter in the center and then spread clockwise. Here you need to first pour little by little around the center and then make a thin dosa out of it. This has to be really thin so that you get crispy ones.
Sprinkle cooking oil on top and cover with a lid. This dosa needs to be cooked with a covered lid and you should not turn it over. So, sim and ensure it gets cooked well. Finally, you can sprinkle ghee for a tastier Tomato Dosa.
Serve with Coconut Chutney. This tastes good with Coconut chutney and not that well with Groundnut.
