Slice off the stems and crown of the brinjals. Cut into quarters.
Soak tamarind in 1/2 cup hot water for 10 minutes. Squeeze well to get the tamarind extract. Filter out and discard the used tamarind.
Keep a cup of water to boil in a pan. Add a pinch of turmeric powder and the tamarind extract to this. Once the water starts boiling- add the quartered brinjal pieces and keep the flame on SIM. Let the brinjals cook for 5-7 minutes in the tamarind water. Once they turn a little tender-drain and remove from pan.
Take all the ingredients for the podi in a pan. Dry roast them, until the dal turns golden brown and the ingredients give out a nice aroma. Rough grind it to maintain the texture of the podi. Remove into a bowl and keep aside.
In a dry non-stick pan, take 2 tsp of oil. Splutter some mustard seeds and curry leaves. Add the podi, fry it in the oil for 5 minutes or so and then add the brinjal. Season with curry powder / sambhar powder and salt. Saute for some more time until the brinjal is completely coated with the podi and the podi looks well fried /golden brown.
Garnish with finely chopped coriander leaves and serve hot with chapatis or sambhar-rice.
