Keep the chopped brinjal in water so that it does not turn black.
Mix the tamarind paste in about 2 cups of water.
Heat oil in a Kadai | Pan over medium-high heat. Once the oil shimmers, add the mustard seeds and let it splutter. Then add the red chillies, curry leaves, channa dahl, urad dahl, and fenugreek seeds. Fry for a second.
Then add the tamarind water and salt. Let it boil until the raw smell of the tamarind goes off and the brinjal gets cooked.
