If you do not have premade cooked rice, make it and then cool completely before starting stove method.
At this stage, squeeze the soaked tamarind to get tamarind juice and add to the seasoning mix. If using tamarind paste add now and add some water; about ½ cup.
Increase the heat and bring the mixture to boil.
Simmer for about 2-3 minutes on medium low heat.
Add the blended spice mixture; stir to combine well. Keep mixing and stir until you get a thick sauce.
Saute a few seconds and add tamarind water or paste with a bit of water.
Stir in tamarind water/tamarind paste with some water, spice mix, jaggery and salt to taste.
Mix well and cook until most moisture is gone. At this stage, if you feel the bottom of the pan is burning, turn the IP off and continue cooking or remove from heat source. The residual heat is enough to fry the tamarind mixture. If needed, splash some water to avoid burnt mixture at the bottom of the pot.
When thick, add drained rice (about 1 ½ cups), 1 ¾ cups hot water; mix well.
