For individual packets of popcorn you will need the following supplies:
about 18 inches of heavy duty aluminum foil
2 T. popcorn
1/2 to 1 T. oil
salt to taste
traditional roasting stick
Lay out the aluminum foil and add the popcorn, oil and salt. Fold the corners of the foil together, folding them over a couple times to get a good seal. Make sure you don’t wrap the foil too tight. You must leave room for the popcorn when it is popped.
Stick the end of a roasting stick into the folds of the aluminum foil at the top of your pouch. It should only take a few seconds for the corn to finish popping. When you hear the popping slow or stop, your popcorn is done. Be careful when opening the pouch to not burn yourself.
