Turn on the Instant Pot, push the saute button, and then the adjust button, this should set your Instant Pot to a higher saute setting. Wait for 2 to 3 minutes until the pot heats up. Add the coconut oil, and when it melts add the popcorn. Add seasoned salt, and stir around to make sure the popcorn is coated with oil and salt. Put a lid on the pot, and once it 2/3rd's of the popcorn turn off the Instant Pot.
