Wash the rice and cook the rice in an Indian pressure cooker or Instant Pot electric cooker.Once cooked, spread it out in a wide plate and let it cool completely, this step helps to achieve separate and non mushy rice. In a Kadai, add oil, once it's hot, add in the peanuts and fry them until they turn slightly golden brown. Take them out and keep them aside.
Then add mustard seeds. Once the seeds stop popping, add in the chana dal, urad dal, and saute for 30 secs till dals turn light golden brown.
Next add curry leaves, dry red chili, green chilies, ginger, asafoetida, and saute for few seconds.
Furthermore add grated mango, turmeric and cook for 2-3 minutes on medium heat. Once cooked turn off the gas.
Now add cooked rice, roasted peanuts, salt, and mix well. You can also add some fresh coconut here.
Sprinkle coriander leaves and serve immediately.
