To make a delicious, low-sugar muscadine jelly using grape juice concentrate as your sweetener, you will utilize the unique properties of [Pomona's Universal Pectin](https://pomonapectin.com/muscadine-grape-jam/). Unlike standard pectins, Pomona's sets using calcium water rather than massive amounts of sugar, allowing you to create an all-fruit jelly. [1, 2, 3]
I've highlighted some popular low-sugar grape recipes from the web, or you can follow the all-fruit Muscadine recipe below.
# # Recipe Overview
*
* Prep time: 30 minutes (plus 2–12 hours for juice straining)
* Cook time: 20 minutes
* Yield: About 4 to 5 cups [3, 4]
*
# # Ingredients
*
* 4 cups prepared muscadine juice (extracted from roughly 4–5 lbs of fresh muscadine grapes)
* 1 cup white or purple grape juice concentrate (100% juice, thawed)
* 2 teaspoons Pomona’s Pectin powder
* 2 teaspoons calcium water (made by mixing ½ tsp of the calcium powder from the Pomona's box with ½ cup of water)
* Optional: 1–2 tablespoons bottled lemon juice (if your muscadines are exceptionally sweet and lack tang) [2, 3, 4, 5, 6, 7, 8]
*
# # Step-by-Step Instructions
1. Extract the Juice: Wash the fresh muscadines. Place them in a large pot with 1 cup of water. Mash them slightly to break the skins. Bring to a boil, then cover and simmer for 10 minutes until soft. Strain the mixture through a damp jelly bag or layers of cheesecloth into a bowl without squeezing the bag to ensure a clear jelly.
2. Prepare Your Canner: Wash and sanitize your jars and lids. Keep the jars warm in your water bath canner.
3. Measure and Mix Base: Measure exactly 4 cups of your extracted muscadine juice into a large saucepan. Stir in 2 teaspoons of the prepared calcium water (and lemon juice, if using).
4. Dissolve the Pectin: Bring your 1 cup of grape juice concentrate to a boil in a small saucepan. Pour the hot concentrate into a blender, add the 2 teaspoons of Pomona's pectin powder, vent the blender lid to let steam escape, and blend for 1 full minute until completely smooth and clump-free.
5. Combine and Boil: Bring the muscadine juice in your main saucepan to a full rolling boil. Pour in the hot pectin-concentrate mixture. Stir vigorously for 1 to 2 minutes while keeping it over high heat to fully incorporate. Once it returns to a full boil, remove it from the heat.
6. Jar and Process: Skim any foam from the surface. Ladle the hot jelly into your warm jars, leaving a 1/4-inch headspace. Wipe the rims clean, apply the lids, and screw bands on fingertip-tight. Process the jars in a boiling water bath canner for 10 minutes (adjusting for altitude if you live over 1,000 feet). [2, 3, 4, 5, 7, 9, 10]
# # Pro Tips for Success
*
* Preventing Crystals: Muscadines are high in tartaric acid, which can form gritty "w**e diamonds" in your finished jelly. To prevent this, let your raw extracted juice sit in the refrigerator for 12 to 24 hours before making the jelly. Strain the cold juice one more time to leave the crystals behind at the bottom of the bowl.
* Choosing the Concentrate: Using 100% white grape juice concentrate preserves the bright, beautiful natural color of bronze scuppernongs, while 100% purple grape juice concentrate deepens the hue of dark muscadines. [3, 6, 7]
*
If you'd like to adjust this batch, let me know:
*
* Are you using dark muscadines or bronze scuppernongs?
* Do you want to adjust the sweetness level up or down?
