Step 1
Inspect 6 half-pint jars for cracks and rings for rust discarding any defective ones. Immerse in simmering water until jelly is ready. Wash new unused lids and rings in warm soapy water.
Step 2
Place apple juice maple syrup cinnamon and nutmeg in a heavy saucepan. Add pectin; bring juice to a rolling boil over high heat until pectin is dissolved. Slowly stir in sugar and bring mixture back to a rolling boil over high heat. Boil for 1 full minute.
Step 3
Remove mixture from heat and skim off foam with a metal spoon.
Step 4
Wipe jars dry and fill with apple jelly. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any spills. Top with lids and screw rings on tightly.
Step 5
Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil cover and process for 15 minutes.
Step 6
Remove the jars from the stockpot and let rest several inches apart 12 to 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool dark area.
