Use Instant Pot models: Ultra 8QT or 6QT DUO to perform the best yield.

Saute mode on Instant Pot . Adjust temperature until it says MORE.

Wait until screen reads HOT. Add oil and popcorn kernels. Stir to coat kernels. Cover with any clear pot lid that fits.

Popcorn will start popping after about 2 minutes. Don't shake the lid because condensation will drip down into popcorn and make it soggy.

After popping slows to about 1 pop every 5 seconds, turn off heat and remove pot.

Pour popcorn into a large bowl and toss with melted butter salt to taste. I use about 2 tbsp melted butter.
