Saute for eight to twelve minutes or until mushy.
Mix in the tamarind paste, fresh coriander, lemon juice, cumin powder, garam masala, a teaspoon of salt, and the processed masala powder you made earlier

Prepare a tadka (tempering oil) by heating two tablespoons of oil or ghee in a pan or large ladle (traditionally known as a Tadka ladle or melting pot)
When the oil/ghee is hot, add a quarter teaspoon of cumin and fenugreek seeds.
As soon as the seeds begin to pop, add two finely chopped red chilis and three to four curry leaves.
When the curry leaves start curling, carefully pour the ghee/oil into the chutney and mix thoroughly.
