In a large sauce pan, combine the apples, water, lemon juice, and spices. Cook until the apples are softened, 5-10 minutes.

Prepare your canning supplies. Bring the temperature of the glass jars up by processing them in hot water for several minutes, and heat a few cups of water in a small saucepan for the lids.

Stir in the pectin until dissolved. Bring back to a boil, and then add in the sugar all at once. Stir in the cranberries and rum. Boil hard for a minute longer.

Skim off any foam and ladle the hot jam into the hot jars, leaving 1/4″ headspace.

Place the lids and bands on top, screwing on the bands just until fingertip-tight. Place the full jars back into the boiling water and process 10 minutes.

Remove from the water and place the jars on a towel. Let the jars cool. The seals should suck down (you should hear a popping noise as they do). Makes 6 eight-ounce jars.
