- Prep Time: 15 minutes
- Cook Time: 1 hour 15 minutes
- Total Time: 1 hour 30 minutes
Step-by-Step Instructions:
Prepare the Fruit: In a large, non-reactive pot (stainless steel or enamel-coated), combine the prepared strawberries and watermelon.
- Detailed Instruction: Make sure the watermelon is completely seeded. Larger seeds will not break down during cooking.
Macerate with Sugar: Add the granulated sugar to the pot and stir well to coat the fruit. Let the mixture sit for at least 30 minutes. This allows the sugar to draw out the natural juices from the fruit, promoting better jam consistency and flavor.
- Timing Tip: You can even do this step ahead of time and let the fruit macerate in the refrigerator overnight for an even more intense flavor.
Simmer the Mixture: Place the pot over medium-high heat and bring the mixture to a rolling boil, stirring constantly to prevent scorching.
- Technique Reminder: A “rolling boil” is one that continues to bubble vigorously even when stirred.
Add Lemon Juice: Once the mixture is at a rolling boil, add the lemon juice. This helps to activate the pectin and preserve the color of the jam.
- Ingredient Notes: Freshly squeezed lemon juice is preferred for the best flavor and acidity.
Cook to Gelling Point: Continue to boil the strawberry watermelon jam, stirring frequently, until it reaches the gelling point. This usually takes about 15-20 minutes.
- Testing for Gelling Point: There are several ways to test for the gelling point. You can use a candy thermometer; the jam should reach 220°F (104°C). Alternatively, you can place a small spoonful of the jam on a cold plate that has been chilled in the freezer for a few minutes. If the jam wrinkles when you push it with your finger, it has reached the gelling point.
Stir in Pectin: Remove the pot from the heat and stir in the liquid pectin. Stir vigorously for 1 minute to ensure it is fully incorporated.
- Important Note: It’s crucial to add pectin after removing from heat; the pectin may clump if not mixed well.
Skim off Foam: Use a spoon to skim off any foam that has formed on the surface of the jam. This will result in a clearer, more appealing final product.
- Why Skim?: Removing any surface foam gives the final jam a clearer appearance.
Jar and Process (Optional): If you plan to store the strawberry watermelon jam for long-term storage, you’ll need to process it in a boiling water bath. Ladle the hot jam into sterilized jars, leaving about ¼ inch headspace. Wipe the rims of the jars clean, place lids and rings on the jars, and tighten until fingertip tight. Process the jars in a boiling water bath for 10 minutes (adjust time for altitude).
- Safety First: Follow proper canning procedures to ensure your jam is safely preserved. If you are new to canning, consult a canning guide for detailed instructions.
(Alternative for shorter use) Cool and Store: If not processing, pour jam into heat safe containers and let cool completely before refrigerating!

- Adjust Sweetness: Feel free to adjust the amount of sugar to your liking. If your fruit is exceptionally sweet, you may want to reduce the sugar slightly.
- Don’t Overcook: Overcooking the jam can result in a thick, gummy texture. Be sure to check for the gelling point frequently.
- Consistency: If you like a smoother jam, use an immersion blender* before adding the pectin.**

FAQs:
Here are a few frequently asked questions about making strawberry watermelon jam:
Can I use frozen strawberries?
- While fresh strawberries are preferred for the best flavor and texture, you can use frozen strawberries in a pinch. Be sure to thaw them completely and drain off any excess liquid before using. This will help prevent the jam from being too watery.
Can I use a sugar substitute?
- It’s possible to substitute the sugar if needed, but be sure to follow the specific recommendations and ratios for that particular substitute in jam or jelly making.
Why didn’t my jam set?
- Several factors can contribute to jam not setting, including not cooking it long enough, not using enough pectin, or using fruit that is not ripe enough. Double-check the gelling point and make sure your fruit is fully ripe. You can also try re-cooking the jam with additional pectin and lemon juice.
