    Onion tomato gotsu recipe Saravana bhavan style

    Onion tomato gotsu, easy to make, but a yummy, tangy side dish that goes well with Idli, dosa and rotis also!

    onion tomato gotsu

    My mom makes with moong dal in this, but my MIL makes this as side dish for chapati. I love it with idli dosa too.

    I have tasted this type of side dish in Saravana bhavan too at time.

    So the colour is appealing. You can use combination of both for flavor.

    Method

    1. Chop onions and tomatoes finely and slit the green chillies and cut into two.
    2. Heat a kadai/heavy bottomed vessel with oil and when oil is hot add the tempering items followed by curry leaves,green chillies and onion.
    3. Fry till onion becomes soft, without changing the color. Add chopped tomatoes and required salt and keep sauteing, till it becomes mushy.
    4. If you are adding red chilli powder, add along tomato.
    saute

    4. Fry in medium flame for 4 minutes and then add ¼ cup water and bring to boil. Simmer for few minutes to form a thick gravy consistency.

    boil

    Transfer to serving bowl and enjoy with idli,dosa or rotis!

    Notes

    • Always add less water.
    • Add a teaspoon of ghee while frying for enhanced taste.
    • Colour purely depends on the colour of the tomatoes, so use red ripe tomatoes and chilli powder (use kashmiri chilli powder) to get the colour. 
    • You can add a mix of green chilli and red chilli powder for flavors.

      Hi, I am Vaneetha. The pictures of Idly and the gravy look so amazing. My mom is an amazing cook, but I am in Australia now and how much ever I try, Idly and dosa dont turn up well. I am not sure if its the quality of rice here or if I am doing something wrong. Can you post how you made such amazing idlis. Thanks.

      Hello, Idly and the gravy looks so amazing. I just tried to find out the receipe for Idly, can you post one. My mom is an amazing cook, but i live in Australia now and how much ever I try, Idly and dosa are coming out miserably. I am a crazy fan of Idly and its been more than 8 months since I had one. Looking forward for your post
