Onion Tomato Gotsu or simply called as Thakkali Kosthu is a side dish that’s served with idli, dosas and pongal that’s popular in my native Kumbakonam and Tanjore.
Some also call it as Quick Thakkali (Tomato) sambar as it gets done very quickly especially when you have guests at home and this one can feed a crowd.

Although myself and the others at home prefer to have Hotel Tiffin sambar with idlis, I prefer making this kosthu during weekdays as it gets done in no time while maintaining the sambar taste as well.
Though there is this Instant Sambar without dal for idli is there, even that requires a little bit of roasting and grinding.
We do like to make the famous Kumbakonam Kadappa whenever we feel like having an aromatic kurma of sorts with idli or dosa.

But when it comes to a side dish to make for a busy weeknight dinner, it is always this gotsu.

There is no need to grind any spices to make this gotsu and it is also not thick as the tiffin sambar or kumbakonam kadappa.
This kosthu is watery like it should be, so as to get absorbed well by the idlis or dosas that we serve it with.
Though it is called as a quick thakkali sambar, do not use it with rice as it won’t taste right.

Always Use standard variety of tomatoes (Naatu Thakkali) to make this gotsu and not the the hybrid ones (Bangalore Thakkali).
Though traditionally paasi paruppu (moong dal ) is used to make this kotsu, you can also use toor dal instead or a combination of both.
While using toor dal, make sure that you cook for an extra whistle as the time taken to cook will be longer than when you cook moong dal.
Onion Tomato Gotsu Recipe details as follows:

Onion Tomato Gotsu Recipe
Ingredients
- Tomato – 3
- Onion – 1
- Yellow Moong dal or Paasi paruppu – 1/4 cup
- Green chili – 3
- Sambar powder – 2 tsp
- Turmeric powder – 1/2 tsp
- Curry leaves – 1 sprig

Instructions
- Wash moong dal and tomatoes. Halve the tomatoes. Place both dal and tomatoes in a pressure cooker and add 1-1/4 cups water and pressure cook for 2 whistles. Wait for the pressure to release.
- After you open the cooker lid, you can find that the skin of the tomatoes have come loose. Just peel them away and discard. Mash the dal along with tomatoes with a masher or pappu guthi and keep aside.
- Chop the onions finely. Cut the green chilies into 3 or 4 pieces.
- Heat a pan with oil. Add mustard seeds and let it splutter. Add onions, green chilies, curry leaves and sauté till the onions turn translucent.
- Add the mashed tomato and dal mixture to the pan and further add 3/4 to 1 cup water to the consistency you want the gotsu to be.
- Add salt, turmeric powder, sambar powder, mix well and let it come to a boil.
- Simmer the flame, add coriander leaves and let it cook for 4 to 5 mins.

I don’t have a pressure cooker, so I boiled the moog dal separately first. I also added some termarind in the end. Turned out well.
