Purchase a bag of fresh popcorn. Make sure that the popcorn you buy is not stale because chances are that stale popcorn would not pop. In case if it does pop, it will have a chewy texture.
Use an airtight glass jar to store the popcorn. Keep the container in a cool, dry place. Keeping the popcorn in a refrigerator may render the kernels too dry or stale, eventually ruining the popcorn.
Reveal the popping chamber by taking off the popping chute from the popper. Measure ½ cup kernels and pour them into the popping chamber.
Melt butter in the popcorn maker if possible. If not, light a stove and melt the butter in a pan. You can even use a microwave for this purpose. Remember that you just want to melt the butter so heat it only for a small amount of time.
Cover the popping chamber with the popping chute that you removed earlier. Beneath the chute, place a 4-quart, heatproof bowl. Make sure that bowl touches the chute’s bottom. If not, raise it up by placing something underneath the bowl. This is important to prevent popped corn from flying all over the room.
Plug the popcorn maker in a power source and wait. The popcorn maker will begin to pop after a while. It should take approximately 3 minutes for the popping to stop. When the popping stops, it is an indication that all the kernels have popped and none remain. Remove the machine from the power source and wait for a few minutes.
Remove the popped corn from the popcorn maker. Spice it up with melted butter and salt. You may want to add other seasonings as well but that will be totally your choice.
