Heat a medium-sized, deep saucepan or stockpot and add 2 tablespoons of Sesame oil ( You can use whatever oil you regularly use, Sesame oil just gives an added flavor).
Once the oil is hot, add ½ teaspoon mustard seeds, ½ teaspoon cumin seeds, 2 broken red chilies, 2 pinches of asafoetida(hing), ¼ teaspoon turmeric powder, and fry for few seconds until the mustard seeds crackle. Then add the curry leaves and fry them until they turn slightly crisp.
Now add the chopped onions and a ⅓ teaspoon of salt for the onions to cook faster and saute for 2 to 3 minutes until the onions start to turn slightly translucent.
Now add 2 teaspoons of ginger-garlic paste, 1 teaspoon of coriander powder, ½ teaspoon of cumin powder, and 1 teaspoon of red chili powder, mix well, and saute for 1 or 2 minutes without burning the spices.
Then add cut bhindi (Okra) pieces and saute on medium-high for 2 to 3 minutes.
Now mix the squeezed tamarind extract with around 1.5 to 2 cups of water and add it to the pot.
Add little less than ½ teaspoon of methi powder, salt to taste, and 1.5 to 2 tablespoons of grated jaggery, mix well, and close the lid. Cook COVERED until bhindi(Okra) pieces are well cooked and all the flavors in the sauce come together. If you want the pulusu to be thicker, then open the lid and cook until you get desired consistency.
Check the seasonings and add anything required. A good pulusu will have a perfect balance of all the flavors like sweet, sour, spice, slightly bitter, and salt.
Add most of the chopped cilantro keeping some for the garnish in the last 2 minutes and cook for another couple of minutes.
Now garnish with cilantro and serve hot with rice, mudda pappu( plain cooked toor dal), ghee(clarified butter), and papad.
