Select the Sauté/Sear function for 12 minutes (lid open); add oil and the whole spices (cinnamon, cloves, cardamom and cumin seeds)
As the spices begin to sizzle, add the curry leaves followed by the onions; mix well and sauté for 5 minutes till the onions turn light brown.
Then add the ground masala; mix well and continue to cook for another 3 minutes. There will be some amount of spluttering so stir continuously.
Mix the spice powders (turmeric, red chilli, coriander and garam masala) in 2-3 tbsp water and add this to the masala. Mix well to combine and cook for one minute.
Add the chicken pieces and season with salt. Also add 2 cups water and mix well to combine.
Select the Pressure cooker (poultry) function and close the lid. Set the timing for 15 minutes, pressure at 40.
After 5 minutes, select the add ingredient function. Open the lid once pressure has dropped and add the potatoes. Mix well and add more water if you desire more gravy.
Close lid and continue pressure cooking process for the remaining 10 minutes.
Once cooking is complete, open lid and garnish with coriander leaves.
