- Set the instant pot into the sauté mode and add the cooking oil. 
- Add the cumin seeds and allow them to splutter and brown a bit. If using Paprika or Kashmiri red chili powder, add it to the oil now. 
- Now add the tomato-spice puree and give a good mix. 
- Allow the mixture to come to a boil (approximately 2-3 minutes). 
- Now add potatoes and mix well. 
- If you like a hot curry, add ½ teaspoon of chili powder at this point, and mix well. 
- Cover and seal the lid. Set the mode to pressure cook and add 3 minutes in the timer. 
- After the beep, wait for 5 minutes more before quick releasing pressure.  
- Open the lid and give a good stir. 
- Now add 1-2 cups of water, and bring the mixture to a boil in the sauté mode. Adjust the consistency as per your preference. I like a runny potato curry than a thick one, so I avoid crushing some potatoes while cooking. 
- Once the curry boils, switch off the instant pot and add chopped cilantro and adjust salt if necessary.  
- Serve hot with poori, rice or naan.
