Use a ladle and large-mounth funnel to evenly distribute the pepper jelly into each jar. To make sure you have an even amount of peppers in each jar, it's best to spoon a ladel into each jar, then following with a second scoop for them all, then more if needed. This batch filled seven 1/2-pint jars for me.
Wipe the rim of each jar to clean off any residue or jelly that may have gotten on them. This is essential--A dirty rim will not create a good seal as the jars cool down. Holding the warm jars with a towel or cooking gloves, place a lid on each jar and tighten the band as tight as possible.
Once you have all your jars filled, bring your canner water back to a boil. If you don't have a jar rack for your canner, place a towel in the bottom to prevent the jars from possibly cracking from exposure to the high heat at the bottom. Once the jars are in place, they need to be in boiling water for 10 minutes.
As the jars cool down, you might hear a sharp click or snap; this sound is made when the center of the lid is drawn down as the content in the jars cools down. After 12 to 24 hours, the bands can be removed, and each jar can be checked to see if the lids have been sealed correctly. Press down with your thumb or finger on the center of the lid. The lid should not push down. If a jar does not seal, the jelly is still good; put it in the refrigerator and make it the first used jar.
