Turn on your pressure cooker /Instant pot (I am using 6qt), press the Saute button.
Press Adjust button to the “More” setting. Once the display reads “HOT”, add the ghee/oil.
Add the popcorn kernels and salt. Toss to coat in the oil then spread evenly. Cover with a glass lid.
Once most of the kernels have popped, turn off the Instant Pot and allow the remaining kernels to pop with the lid on.
Once the kernels stop popping remove the lid, season with the desired seasoning or keep it as is and serve.
