In an Instant pot on saute mode, heat some oil and cook the potato wedges till they are half done, remove and keep aside

In the same oil add the onions and the salt

When the onions are halfway caramelized, add the chillies

Add the meat, the ginger and garlic paste, followed by the Garam Masala and the chilli powder

Mix everything to coat

Add the water, cover, cancel saute mode and set the IP to pressure cooker mode for 30 mins

Once the timer is done allow the pressure and steam to naturally release and open the lid

Set the IP to saute mode again, taste for salt and add salt to taste

Now return the half cooked potatoes back to the gravy, place the lid partially over the pot and finish cooking the potatoes
