Ingredient Checklist


Instructions Checklist
  • Thinly slice apples (do not peel or core). Put into a large kettle along with the water. Over high heat, bring to a boil, then lower heat to a simmer. Stir and mash apples occasionally, cooking until very soft.

  • Pour mixture into a moistened jelly bag or a strainer lined with several layers of cheesecloth and let strain overnight.

  • Put pulp in a saucepan and add half the juice (store remaining juice in refrigerator; it will be used later). Over low heat, simmer for 1 1/2 hours. Strain through jelly bag a second time. (It might not need to strain as long as the first time.)

  • Discard pulp and add reserved juice. If using within a week, store in refrigerator. For longer storage, heat, pour into hot, sterilized jelly jars, and seal.
