Homemade Muscadine Jam

Follow our step-by-step guide on how to make Homemade Muscadine Jam.

1. Step 1

   Before you dive into making your delicious muscadine grape jam, start by inspecting your jars.

2. Step 2

   Whether you’re using four 8-ounce jars or two 16-ounce jars, check for any cracks and ensure the rings are rust-free.

3. Step 3

   If you find any defects, it’s best to toss those jars aside.

4. Step 4

   To keep your jars ready for filling, immerse them in simmering water until you’re ready to pour in that sweet jam.

5. Step 5

   Don’t forget to wash your new lids and rings in warm, soapy water to keep everything clean and safe.

6. Step 6

   While you’re at it, pop a couple of small plates in the freezer.

7. Step 7

   These will come in handy later for testing the jam’s consistency.

8. Step 8

   Now, let’s get to the star of the show: the muscadine grapes! Give them a good wash and slice them in half.

9. Step 9

   In a large pot, combine the grapes with sugar over medium heat, stirring gently as you bring the mixture to a boil.

10. Step 10

    Once it’s bubbling away, maintain a medium to low boil for about 15 to 20 minutes.

11. Step 11

    Stir often to prevent any sticking, and keep an eye on the temperature to avoid scorching.

12. Step 12

    To check if your jam is ready, drop a small spoonful onto one of those frozen plates.

13. Step 13

    Let it sit for a minute or two; if it gels up nicely, you’re good to go! If it’s still looking a bit runny, just keep cooking it a little longer.

14. Step 14

    Next, it’s time to blend! Carefully transfer a portion of the jam mixture to a blender and puree it until all the hulls and seeds are finely ground.

15. Step 15

    Keep this pureed jam warm in a pot while you finish up the rest of the mixture.

16. Step 16

    Now, it’s time to pack that delicious jam into your hot, sterilized jars.

17. Step 17

    Fill each jar to about 1/4 inch from the top.

18. Step 18

    To ensure a perfect seal, use a clean knife or thin spatula to remove any air bubbles by running it around the inside of the jars.

19. Step 19

    Wipe the rims with a damp paper towel to clear away any residue before placing the lids on and screwing the rings tightly.

20. Step 20

    For the final step, grab a large stockpot and place a rack at the bottom.

21. Step 21

    Fill the pot halfway with water and bring it to a boil.

22. Step 22

    Carefully lower your filled jars into the boiling water using a jar holder, making sure they’re at least 2 inches apart.

23. Step 23

    Add more boiling water until it covers the jars by at least an inch.

24. Step 24

    Bring everything back to a rolling boil, cover the pot, and let it process for 5 to 10 minutes.

25. Step 25

    Once the time is up, carefully remove the jars from the water and set them aside to cool completely.

26. Step 26

    As they cool, listen for the satisfying ‘pop’ of the jars sealing—this means your jam is ready for storage! Allow at least an hour for them to seal properly.

27. Step 27

    Finally, store your sealed jars in a dark, cool place, and get ready to enjoy the fruits of your labor! Your homemade muscadine grape jam is sure to be a delightful treat.
