Making homemade jam is a delightful way to preserve the taste of summer, and this Watermelon Jam recipe is a perfect example of that. My love for watermelon jam started on a sunny afternoon during a family picnic at the beach. My sister brought a jar of her homemade watermelon jam, and from the first spoonful, I was hooked. The sweetness of the watermelon combined with the tanginess of lemon juice created a refreshing burst of flavor that was both nostalgic and novel.

This Watermelon Jam recipe is wonderfully simple, making it an ideal project for both beginners and seasoned jam-makers. The ingredient list is short, and the process is straightforward. You start with fresh watermelon puree, which is naturally sweet and hydrating. Adding lemon juice not only balances the sweetness but also helps in preserving the vibrant color and enhancing the overall flavor.

One aspect I particularly love about this recipe is its versatility. While the basic ingredients yield a delicious jam, there are many ways you can tweak it to suit your taste. For instance, if you prefer a less sweet jam, you can reduce the amount of sugar or use a sugar substitute. You can also infuse the jam with additional flavors. A pinch of cinnamon or a splash of vanilla extract can add a new dimension to the taste. For a bit of a kick, consider adding a small amount of finely chopped mint or basil.

The use of powdered pectin labeled ‘low sugar’ or ‘no sugar needed’ is key to achieving the right consistency without relying on too much sugar. This makes the jam not only delicious but also a bit healthier compared to traditional high-sugar jams. The pectin helps the jam set properly, giving it a delightful spreadable texture that’s perfect for toast, pastries, or even as a topping for ice cream.

As you embark on making this Watermelon Jam, remember that it’s a recipe that invites experimentation. Feel free to adjust the sweetness, add spices, or even mix in other fruits like strawberries or raspberries for a unique twist. This jam is best enjoyed with loved ones, bringing a taste of summer to your table no matter the season. Happy jamming!

Making Watermelon Jam


  • 1/4 cup lemon juice
  • 2 cups of watermelon puree
  • 6 tablespoons powdered pectin (marked ‘low sugar’ or ‘no sugar needed’)
  • 2 cups white sugar


  1. In a pot, mix the watermelon puree, lemon juice, and sugar together. Heat until it comes to a robust boil, then reduce the heat to a simmer.
  2. Swiftly incorporate the pectin, whisking it in thoroughly with a hand whisk or fork to avoid clumps.
  3. Turn the heat back up to bring the mixture to a boil again, then reduce to simmer. Stir the mixture every minute for approximately 20 minutes.
  4. Pour the watermelon jam into a mason jar. The jam will set completely as it cools.
  5. Refrigerate the watermelon jam for up to a month, or use canning methods for extended storage.


What is the best way to puree watermelon for this jam?

To puree watermelon, remove the seeds and rind, then blend the flesh in a blender or food processor until smooth. You may strain the puree to remove any pulp for a smoother consistency.

Can I use regular pectin instead of low or no sugar needed pectin?

Yes, you can use regular pectin, but you might need to adjust the amount of sugar and follow the specific instructions on the pectin package for best results.

How can I tell when the jam is ready to be transferred to jars?

The jam is ready when it thickens and clings to the back of a spoon. You can also test by placing a small amount on a cold plate; if it sets and wrinkles when pushed, it is ready.

Can I freeze watermelon jam?

Yes, you can freeze watermelon jam. Ensure it is in a freezer-safe container, leaving some space for expansion. It can last up to a year in the freezer.

What can I do if my jam doesn’t set properly?

If your jam doesn’t set, you can reheat it and add a bit more pectin. Boil for a few more minutes, then test for the proper consistency before jarring again.
