Ingredients
4 cups fresh watermelon (seedless and diced)
1 tbsp lemon juice (for acidity and preservation)
½ cup sugar (adjust to taste)
1 tbsp pectin (optional for thickness)
Step-by-Step Instructions:
Step 1: Prepare the Watermelon

- Cut and dice fresh, seedless watermelon. Remove all black seeds. Measure 4 cups of diced fruit.
Step 2: Blend the Watermelon

- Add watermelon to a blender or food processor. Blend until smooth. You can strain the puree for a smoother texture, or leave it as is for a chunky jam.
Step 3: Cook the Puree
- Pour the watermelon puree into a saucepan. Add lemon juice and sugar. Stir well.
Step 4: Simmer on Low Heat

- Bring the mixture to a boil, then reduce to low heat. Stir often and let it simmer for 30-40 minutes until it thickens. Add pectin if desired for faster setting.
Step 5: Check the Consistency
- To test the jam, place a small spoonful on a cold plate. If it gels or wrinkles when touched, it’s ready.
Step 6: Store Your Jam

- Let it cool slightly. Pour into clean, sterilized glass jars. Seal tightly. Store in the fridge for up to 2-3 weeks.
Tips:
- For a sugar-free watermelon jam, use stevia or natural sweeteners.
- Add mint or lime zest for a twist in flavor.
- Great on toast, pancakes, yogurt, or as a summer fruit preserve.

FAQs About Watermelon Jam
Q1: Can I make watermelon jam without pectin?
Yes, you can. Just simmer the watermelon puree longer to naturally thicken it. Lemon juice helps it set and preserves it.
Q2: How long does homemade watermelon jam last?
When stored in a clean, airtight jar in the fridge, it lasts up to 2 to 3 weeks. For longer storage, use proper canning methods.
Q3: Can I make sugar-free watermelon jam?
Absolutely! Use natural sweeteners like stevia, monk fruit, or erythritol. Adjust amounts to taste since these are sweeter than sugar.
Q4: Does watermelon jam taste like jelly or preserves?
It has a light, fruity, and refreshing taste—less tart than strawberry or raspberry jam. You can keep it smooth like jelly or leave small fruit bits for a preserve-style texture.
Q5: Can I freeze watermelon jam?
Yes! Let the jam cool, pour into freezer-safe containers (leave space for expansion), and freeze for up to 3 months.
Q6: Why is lemon juice used in watermelon jam?
Lemon juice adds acidity which helps the jam set and also acts as a natural preservative to prevent spoilage.
Q7: My jam is too runny. How do I fix it?
Reheat and simmer longer to reduce liquid. You can also add more pectin or a tablespoon of chia seeds as a natural thickener.
Q8: Can I use frozen watermelon for this jam?
Yes, frozen watermelon works too. Just thaw it completely and drain excess water before blending.

Yes. Remove all black seeds. White seeds are soft and usually blend easily, but it’s best to remove them if possible.
Q10: What’s the best way to thicken watermelon jam naturally?
Simmer the jam slowly to let the water evaporate. You can also add a tablespoon of chia seeds or use lemon juice to help it thicken.
Q11: Can I use this jam for cakes or desserts?

Watermelon has a high water content. Cook it longer on low heat to reduce the liquid and bring out the flavor.
Q13: Is watermelon jam healthy?
Yes, when made at home. It has fewer additives, and you can control the amount of sugar. Watermelon is rich in vitamin C and hydrating nutrients.

Yes. Use proper water-bath canning methods and sterilized jars. This way, the jam can last for several months in a cool, dry place.
