I didn’t use the Instant Pot glass lid, one of the glass lids of my cooking pan fit well on the Instant pot hence I used that. Make sure to use a lid that fits well.
Popcorn is made in the Saute mode in more temperature setting, moisture will build up under the glass lid and there will be slight dripping through the lid, just wipe it off using a kitchen towel and be careful while opening the lid- wear an oven mitt.
I used organic refined coconut oil that can be used for medium high heat.
Since, the temperature is kept at more or high, you have to use an oil with high smoke point (Smoke point refers to the temperature at which an oil starts to burn and smoke).
Avoid using extra virgin coconut oil and extra virgin olive oil- these have low smoke points.
Pop 1/2 cup to 3/4 cup of corn kernels at a time. Do not use more that this as there will be a lot of unpopped kernels left in the pot.
