Ruby Red Grapefruit Marmalade

Follow our step-by-step guide on how to make Ruby Red Grapefruit Marmalade.

1. Step 1

   Start by inspecting two 5-ounce jars for any cracks and checking the rings for rust.

2. Step 2

   If you find any defects, it’s best to discard them.

3. Step 3

   Once you’ve ensured your jars are in good shape, immerse them in simmering water to keep them warm while you prepare the marmalade.

4. Step 4

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

5. Step 5

   Next, give your grapefruits a good wash and dry.

6. Step 6

   For two of the grapefruits, grab a zester and create beautiful ribbons of zest, setting them aside for later.

7. Step 7

   With the other two grapefruits, use a sharp paring knife to carefully cut away thin strips of peel.

8. Step 8

   Make sure to remove all the bitter white pith from the fruit and toss it aside.

9. Step 9

   Now, slice the grapefruits into lovely wheels and remove any pesky seeds you come across.

10. Step 10

    In a non-reactive saucepan, combine the grapefruit wheels and zest strips with sugar, stirring well to coat the fruit evenly.

11. Step 11

    Heat the mixture over medium-high heat until it starts bubbling, stirring constantly to prevent sticking.

12. Step 12

    As the fruit heats up, gently smash it until it liquefies.

13. Step 13

    Once bubbling, reduce the heat to low and maintain a steady boil, stirring often.

14. Step 14

    If you notice any white froth forming on the surface, skim it off.

15. Step 15

    Keep cooking for about 10 minutes, or until the marmalade thickens enough to coat the back of a spoon.

16. Step 16

    Now it’s time to add those fragrant zest ribbons to the pot and let everything cook together for an additional 5 minutes.

17. Step 17

    To check if your marmalade has reached the perfect consistency, place a small spoonful on a plate and pop it in the freezer for about 3 minutes.

18. Step 18

    If it’s just right, remove the pot from the heat.

19. Step 19

    Carefully pack the hot marmalade into your sterilized jars, filling them to within a quarter inch of the top.

20. Step 20

    Use a clean knife or thin spatula to gently remove any air bubbles trapped inside.

21. Step 21

    Wipe the rims of the jars with a damp paper towel to ensure a good seal, then secure the lids and screw the rings on tightly.

22. Step 22

    For the next step, place a rack in the bottom of a large stockpot and fill it halfway with water.

23. Step 23

    Bring the water to a boil, then lower the jars into the pot, making sure they’re spaced about 2 inches apart.

24. Step 24

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

25. Step 25

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

26. Step 26

    Once the time is up, carefully remove the jars from the stockpot and let them rest on a clean surface, spaced several inches apart, for 24 hours.

27. Step 27

    After this time, gently press the center of each lid to check if it’s sealed properly; it shouldn’t move up or down.

28. Step 28

    Finally, remove the rings for storage and keep your beautifully crafted jars of grapefruit marmalade in a cool, dark place.

29. Step 29

    Enjoy the sweet satisfaction of your homemade creation!.
