Do not use your microwave's popcorn button. Preparation times vary by appliance, these are guidelines only.
Steps
Remove the plastic overwrap and unfold the bag. Place it in the center of the microwave with the directions side facing up and the seam at the top.
Set the microwave to HIGH for 1 minute 30 seconds to 2 minutes 30 seconds.
Stay near the microwave. Stop it as soon as popping slows to 1 to 2 seconds between pops.
Do not let the popcorn overcook. Scorching or burning can result.
The bag will be hot. Remove it carefully and open the top away from your face, pulling slowly at the diagonal corners.
Caution: Hot steam will escape when opening the bag. Keep your face and hands clear of the opening.
Microwave wattages vary. If popping is slow to start or the bag hasn't fully popped by the maximum time, check your microwave's wattage against the manufacturer's guidance rather than extending the time further.
