Nothing tastes quite like summer as much as watermelon jelly. This recipe is a playful twist on classic jams and is a perfect way to capture the sun-ripe sweetness of watermelon for months to come. With a whisper of lime and the vibrant color of peak season melons, watermelon jelly brings fresh flavor to your morning toast, yogurt bowls, or even just dolloped onto a spoon when no one's looking.
Every batch I make brings back memories of backyard picnics and sticky summer smiles. The flavor is so nostalgic that now I put up extra jars each year to gift to friends.
Ingredients
- Fresh seedless watermelon, chopped with rind removed: Choose a melon that smells sweet and feels heavy for its size
- White granulated sugar: This is your classic jelly sweetener and helps set the texture
- Bottled lime juice or fresh limes: Bottled juice ensures food-safe acidity but I love the brightness of fresh-squeezed
- Sure Jel Low Sugar Pectin: This pectin needs less sugar than classic types making the jelly fresher tasting
Instructions
- Prepare the Watermelon:
- Chop enough seedless watermelon to make 6 to 8 cups with rind removed. The riper the fruit the juicier your jelly will be.
- Juice the Watermelon:
- Blend all watermelon chunks until smooth. Strain the purée through a double layer of cheesecloth or a jelly bag. This step ensures a crystal-clear jelly without pulp.
- Measure and Reserve:
- Pour the strained liquid into a measuring cup. You will need exactly 4 cups of juice. Set aside any extra for a refreshing drink.
- Combine and Boil Juice with Lime and Pectin:
- Pour the 4 cups of watermelon juice into a large saucepan. Add the lime juice and pectin. Bring this mixture to a full boil over medium-high heat whisking constantly to dissolve the pectin.
- Initial Boil:
- Continue to boil the juice-lime-pectin mixture for exactly one minute. This step activates the pectin for a solid set.
- Add Sugar and Final Boil:
- Whisk in all the sugar at once. Stir until fully dissolved. Return to a hard boil and leave it bubbling for one more minute.
- Jar the Jelly:
- Ladle the scalding hot jelly mixture into clean hot jars leaving a small space at the top for headroom. Clean up any drips on the rim with a towel.
- Seal and Store or Can:
- Place lids on each jar screwing them until fingertip tight. For refrigerator jelly just chill and allow 12 to 24 hours for a perfect set. For long term storage process jars in a boiling water bath as needed for your altitude.

My favorite part is the first taste test on a warm biscuit It always surprises me how pure and gentle the watermelon flavor remains. My kids now insist on helping with the jarring so it is become a real family tradition in our kitchen.
