Homemade Nectarine Jam

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

1. Step 1

   Begin by carefully inspecting five half-pint jars for any cracks and checking the rings for rust; discard any that show signs of damage.

2. Step 2

   Immerse the jars and rings in simmering water to keep them warm while you prepare the jam.

3. Step 3

   For new lids, wash them in warm, soapy water to ensure they are clean and ready for sealing.

4. Step 4

   Measure out approximately 4 1/2 cups of finely chopped nectarines and immediately mix them with lemon juice in a heavy pot to prevent browning.

5. Step 5

   In a separate small bowl, blend 1/4 cup of sugar with the fruit pectin, then add this mixture to the nectarines, stirring thoroughly.

6. Step 6

   Gradually bring the mixture to a vigorous rolling boil that continues to bubble even when stirred.

7. Step 7

   Once boiling, add the remaining 2 ¾ cups of sugar, stirring to dissolve and scraping the bottom of the pot to prevent sticking.

8. Step 8

   Maintain a constant stir and boil for exactly one minute.

9. Step 9

   After a minute, remove the pot from heat and stir in the almond extract for a delightful flavor boost.

10. Step 10

    Carefully pack the jam into your prepared jars, filling them to within 1/4 inch from the top.

11. Step 11

    Use a clean knife or thin spatula to eliminate any air bubbles by running it around the inside of the jars.

12. Step 12

    Wipe the rims with a damp paper towel to remove any spills, then place the lids on top and screw the rings on tightly.

13. Step 13

    In a large stockpot, place a rack at the bottom and fill it halfway with water.

14. Step 14

    Bring the water to a boil, then lower the jars into the pot, ensuring they are spaced at least 2 inches apart.

15. Step 15

    Add more boiling water to cover the jars by at least 1 inch, then bring to a rolling boil, cover, and process for 10 minutes.

16. Step 16

    Once done, carefully remove the jars from the stockpot and set them on a cloth-covered or wooden surface, allowing space between each jar.

17. Step 17

    Let them rest undisturbed for 24 hours.

18. Step 18

    After this time, gently press the center of each lid to check for a proper seal; it should not move up or down.

19. Step 19

    Finally, remove the rings for storage and keep the jars in a cool, dark place, ready to enjoy your homemade nectarines jam.
