Have your water bath canner, jelly jars, lids, and rings ready. Jars, lids, and rings should be clean. The water in the canner should be hot but not boiling.
Ladle hot jelly into hot half-pint or jelly jars, leaving 1/4 inch headspace at the top.
Remove trapped air bubbles, wipe rims with a dampened cloth, put lids and bands on the jars. (Be careful because the jars will be very hot.) Tighten the bands to fingertip-tight.
Slowly lower the hot jars into the hot water bath canner making sure that they are covered by at least 1 inch of water. Add the canner lid, bring to a boil, and process for 10 minutes (adjusting for your altitude, if necessary).
After 10 minutes, turn off the heat, remove the canner lid, and wait for 5 minutes. Then carefully remove the jars and let them cool for 12 to 24 hours, undisturbed. After that time, remove the bands and confirm that the lids have sealed to the jars. Label and store your jelly.
