Pop corn can be traced back as the 1500.
The reason popcorn pops was clarified by native Aztecs. There are spirits who reside within the kernels of popcorn. As you heat these spirits houses, they get mad. Eventually, the spirits get so mad they pop out of there homes as unhappy little puffs of steam.
Evidently, this was folk lore and we’ve since discovered scientifically how popcorn pops. It’s relatively simple. Inside the kernel is a soft patch of starch with approximately 14% moisture. The moisture is comprised by kernels hard outer shell.
With no moisture, pop corn will not pop. The best way to store popcorn is air tight containers and stored in a cool place like your cupboard or pantry.
Eventually the hard surface gives way and the popcorn explodes. The soft heated starch burst, turning in side out.
Bear in mind a fridge can most likely dry out your popcorn. If you find that your pop corn has dried out, you can rejuvenate them and still can get them to pop. Place the kernels in a jar a fill it full of water. It takes about three days but the water will re moisturize the kernel and that will cause the kernels to pop.
