For your last pepper harvest of the season, pick every pepper, no matter how small. Sort the peppers by size. Any pepper approximately the size of your fist can become a mini pepper cup. Smaller peppers can be diced and dehydrated, or simply used fresh in soups, stews, chilies, however you like them. Any large peppers, just use as you normally would.
Rinse the peppers, slice off the top and clean out the seeds. You won't be using the tops for this project, but you can dice them into small pieces to use fresh.
Bring a pot of water to a boil, and drop the peppers in to blanch for no more than two minutes. With a slotted spoon, quickly lift them out of the boiling water into a large bowl of icy water to stop the cooking process.
Arrange the blanched peppers on a cookie sheet. Make room in your freezer to accommodate the cookie sheet. You can use smaller dishes if absolutely necessary. Freeze for 5 hours, until rock-hard.
Carefully place the frozen pepper cups into plastic bags, and store them in the freezer. When needed, just take out as many cups as you wish to stuff.
