Apple jam with cinnamon

Peel the apples.

Place the peels in a wide pot for boiling jam and add 2 cups of water. Boil for 15 minutes.

Take the apple peel out of the water, it won't be needed anymore.

Cut the apples into cubes.

Grate the zest of 1 lemon on a fine grater, avoiding the white part: it is bitter.

Put the apples with the peel in the basin where the skins were boiled.

Squeeze juice from the lemon.

Add sugar, a cinnamon stick, and lemon juice to the bowl.

Cook on medium heat for 1 hour and 45 minutes. Stir the jam every 15 minutes.

Distribute the ready jam into jars, remove the cinnamon stick.
