How to Make Watermelon Jam

Step 1: Prepare the Watermelon

  • Add the fresh watermelon pieces to the instant pot.
  • Also add the sugar and lemon juice.

Step 2: Stir Ingredients

  • Stir the contents well. If any seeds are present, they will float to the top for easy removal.

Step 3: Cook Under Pressure

  • Close the instant pot lid in sealing position. Cook on high pressure for 15 minutes.
  • Wait for a natural pressure release. Once released, carefully open the lid.

Step 4: Mash the Mixture

  • Stir and mash the contents using a potato masher. Add the vanilla extract, stirring it in well.

Step 5: Simmer for Thickness

  • Use the sauté function to simmer while stirring and mashing for about 10 to 12 minutes. Remove any floating seeds as needed.

Step 6: Create Cornstarch Slurry

  • To thicken the mixture, take about 3/4 cup of liquid from the pot. Mix with cornstarch to create a slurry free of lumps.

Step 7: Final Cooking Phase

  • Add the cornstarch mixture back to the instant pot and stir quickly to incorporate it evenly.
  • Continue simmering for another 4 to 5 minutes until it thickens into a jam consistency.

Step 8: Cool Down Process

  • Press cancel on the instant pot. Transfer it to a cool surface to stop further cooking.

Step 9: Store Your Jam

  • Once slightly cooled, transfer your watermelon jam into airtight dry glass jars. Store in the refrigerator for up to two weeks or freeze if desired.

How to Perfect Watermelon Jam

Perfecting your watermelon jam can take it from good to great. Here are some tips to ensure your jam turns out amazing every time.

  • Choose ripe watermelons: The sweeter the fruit, the better the flavor of your jam. Look for watermelons that feel heavy for their size and have a uniform shape.
  • Adjust sugar to taste: Depending on your preference, you can reduce the sugar in the recipe. Just remember that sugar helps with preservation and texture.
  • Watch the simmering time: Keep an eye on the cooking process. Simmering too long can lead to overly thickened or burnt jam.
  • Use fresh lemon juice: Fresh lemon juice not only enhances flavor but also helps balance sweetness and aids in setting the jam.
  • Store properly: Allow the watermelon jam to cool completely before transferring it to airtight jars. This helps maintain freshness longer.

Best Side Dishes for Watermelon Jam

Pairing side dishes with your watermelon jam can create a well-rounded meal experience. Here are some excellent options that complement its sweet flavor:

  1. Cheese Platter: Include varieties like cheddar, gouda, and blue cheese for an exciting taste contrast.
  2. Savory Biscuits: Flaky biscuits work wonderfully as a base for spreading watermelon jam.
  3. Greek Salad: A fresh salad with olives, feta, and cucumbers balances out the sweetness of the jam.
  4. Grilled Chicken: Serve alongside grilled chicken breast topped with watermelon salsa for a summer feast.
  5. Pork Chops: Glaze pork chops with watermelon jam while grilling or baking for added flavor.
  6. Vegetable Crudités: Crunchy veggies like carrots and cucumbers provide a refreshing side option when served with dip options alongside watermelon jam.

Common Mistakes to Avoid

Making watermelon jam can be delightful, but there are common pitfalls that can affect the final product.

  • Overcooking the Watermelon: Cooking the watermelon too long can lead to a mushy texture. Keep an eye on the cooking time and aim for a jelly-like consistency.
  • Using Too Much Sugar: While sugar enhances flavor, using excess can overpower the natural taste of watermelon. Follow the recipe’s sugar amount and adjust to your preference after tasting.
  • Ignoring Seed Removal: Leaving seeds in the jam can create an unpleasant texture. Be sure to remove seeds as they float to the top during cooking.
  • Skipping the Cornstarch Slurry: Not using a cornstarch mixture may result in runny jam. This step is crucial for achieving a thick, spreadable consistency.
  • Not Storing Properly: Improper storage can spoil your watermelon jam quickly. Use clean, airtight containers and refrigerate or freeze as directed.

Storage & Reheating Instructions

Refrigerator Storage

  • Store watermelon jam in clean, airtight glass jars.
  • The jam will last up to two weeks in the refrigerator.

Freezing Watermelon Jam

  • For longer storage, transfer the jam to freezer-safe containers.

  • Microwave: Heat in short intervals of 15-20 seconds, stirring in between until warmed through.
