Switch on your Instant Pot, choose sauté setting and select more or high depending on your Instant Pot model .
Leave it on till the display says high and then add the coconut oil and let it melt completely and begin to sizzle.
Add 3 popcorn kernels and stir the kernels are coated with oil and cover the pot.
When the kernels start to pop then you add the rest of the kernels and use a spatula to mix till they are all coated.
Cover with a glass lid, leaving slightly ajar and the popcorn will start popping in about 3 mins.
During popping, lift out the Instant Pot insert and gently swirl so that the unpopped kernels drop to the bottom. Do this a couple of times so that more kernels pop this way.
In about 4-5 min the popping will slow down so turn of the Instant pot then, wait for 30 seconds for any final pops and then decant the popcorn into a large bowl.
Add any seasonings you desire, mix and serve.
