Heat a saucepan on a medium flame for 2 minutes. Add cooking oil and when it is slightly heated up, add mustard seeds.
2 tsp mustard seeds, 4 tbsp cooking oil
Wait for a few seconds until it starts crackling and popping. Then add cumin seeds, curry leaves, and whole dry red chilies at the same time. Fry these for 1 minute and then add the mangoes along with the water.
1 tsp cumin seeds, 5 dry red chilies, 10 curry leaves
Now add the rest of the ingredients like salt, jaggery, green chilies, tamarind juice, masala paste from the grinder, and half a cup of water. Stir well until everything comes together and the curry starts to simmer.
1/2 tsp salt, 1 tbsp grated jaggery, 2 tbsp tamarind juice, 2 green chilies
At this stage, you need to taste the curry and adjust the seasoning. Place the lid and cook on low flame for about 10 to 12 minutes.
Once the curry is cooked well, serve hot with steamed rice or roti.
