Muscadine Grape Jam

Muscadine Grape Jam is a low-sugar or low-honey cooked jam made with Pomona’s Universal Pectin. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener.

Notes

Muscadine Grape Butter (pulp and juice, no skins) — use this recipe for Concord Grape Butter.
Servings 5 cups

Ingredients

  • 4 cups prepared muscadine grapes see Steps 3 through 6 below
  • 4 teaspoons calcium water see step #1
  • ½ cup up to 1 cup honey or ¾ cup up to 2 cups sugar
  • 2 teaspoons Pomona’s Pectin mixed with sweetener

Instructions

  • Before you begin, prepare calcium water.
    To do this, combine ½ teaspoon calcium powder (in the small packet in your box of Pomona’s pectin) with ½ cup water in a small, clear jar with a lid. Shake well.
    Extra calcium water should be stored in the refrigerator for future use.
  • Wash jars, lids, and bands. Place jars in canner, fill canner 2/3 full with water, bring to a boil. Turn off heat, cover, and keep jars in hot canner water until ready to use. Place lids in water in a small sauce pan; cover and heat to a low boil. Turn off heat and keep lids in hot water until ready to use.
  • Wash the grapes. Then score the end of each grape with a paring knife and pop the flesh out of the skin and into a sauce pan. Place the skins in a bowl and set aside.
  • Bring the skinless grapes to a boil and simmer until soft, about 10 minutes. Put the simmered grapes into a Foley mill or a fine sieve and push the pulp and juice through into a bowl, leaving behind the seeds. Discard the seeds.
  • Place the skins in a sauce pan with just enough water to keep them from sticking to the bottom of the pot. Bring to a boil and simmer until soft and tender (10 to 15 minutes). Puree the skins in a blender or food processor.
  • Add processed skins to the bowl of pulp and juice and stir together well. Measure 4 cups of this mixture into a sauce pan.
  • Add calcium water, and mix well.
  • Measure sugar or room temperature honey into a bowl. Thoroughly mix pectin powder into sweetener. Set aside.
  • Bring fruit mixture to a full boil. Add pectin-sweetener mixture, stirring vigorously for 1 to 2 minutes to dissolve the pectin while the jam comes back up to a boil. Once the jam returns to a full boil, remove it from the heat.
  • Fill hot jars to ¼” of top. Wipe rims clean. Screw on 2-piece lids. Put filled jars in boiling water to cover. Boil 10 minutes (add 1 minute more for every 1,000 ft. above sea level). Remove from water. Let jars cool. Check seals; lids should be sucked down. Eat within 1 year. Lasts 3 weeks once opened.

    If I’ve finished and don’t like the texture, can I redo by removing and using immersion blender to more finely chop skins? If so, what do I do about the pectin/sugar in a redo? I love being able to do jam so quickly without having to wait to reach a high temp like I did with my fig preserves before I discovered Pomona!

      Hello Dale,

      You sure can! You can empty your jars, make your adjustments to the texture and then place the jam back into a sauce pan. Bring to a boil, then fill into clean, hot jars. You will then reprocess your jars in water-bath canner.

      Happy jamming!

    My muscadine are small so scoring and popping off skins isn’t feasible…… any instructions for just the sieved pulp ?

      You will just need to decrease the pectin amount by 1/2 teaspoon. Happy jamming!

      You can boil the muscadines whole.. The skins will crack and some may even fall away from the meat.. Becareful not to break the meat to release the seeds. Once pot of cooked grapes are cooled down,, separate the skins and place in processor..

    How many muscadines will you need to yield 4 cups of prepared mixture?

      Hello Lee,

      We are not certain, as there are so many variables! We guessing that it will be between 3-5 pounds.
