Tomato Pickle / Thakkali Urugai

Tomato season here...we now get tomatoes for just 10 Rs / kg...:)
Thought to make some urgai/Pickle out of it so made it...

Ingredients:
Tomato - 1 kg
Asafoetida - 1 tsp
Mustard+Urud dal - 2 tsp
Curry leaves few
Chilly powder or Sambar powder - 5 tsp (Can alter as per ur spice req)
Turmeric powder - 1/4 tsp
Salt to taste
Gingelly Oil / Sesame Oil - 150 gm

Method:

Wash Tomatoes, cube it and blend in mixer to puree.
Heat a pan (best non stick) with oil.
Temper with mustard, asafoetida, curry leaves.
Add Tomato puree, turmeric, Salt and Sambar powder.
I used Sambar powder instead of chilly powder.
Close the pan with lid and allow to cook for 1 hour in low fire.
In the meanwhile stir it so that it will not get burnt.
The mixture will get reduced and the quantity will be 25% .
And you can see the pickle emits oil out of it at this stage switch off.
Allow to cool and store in bottle.
