How to Make Raspberry Freezer Jam
Step-by-Step Stovetop Instructions
Making raspberry freezer jam is incredibly straightforward. Start by combining the raspberries, sugar, lemon juice, and cornstarch in a saucepan over medium heat. Stir until the sugar has fully dissolved. Then, bring the mixture to a boil.

Once boiling, reduce the heat to medium-low and let it simmer. Stir occasionally while mashing any large berry chunks. This process should take about 10-12 minutes. You’ll notice the mixture thickening beautifully!
Achieving the Perfect Jam Consistency
Check the jam’s thickness by coating the back of a spoon. It should be thick enough to leave a mark. If it’s too thin, consider adding a cornstarch slurry. If it’s too thick, a splash of water can help bring it to the right consistency. Remember, the jam will thicken even more as it cools!
Tips for the Best Freezer Jam
Freezing and Storage Guidelines
When you’re ready to store your jam, transfer it to clean jars, leaving about ½ inch of headspace to allow for expansion. This raspberry freezer jam can be refrigerated for up to 3 weeks or frozen for up to a year. Make sure to let the jam cool completely before sealing the jars with lids!
Sweetness and Sugar Options
If you prefer a less sweet jam, feel free to reduce the sugar content. Just remember to taste test before jarring to ensure it meets your flavor preference. Keep in mind that lower sugar options won’t last as long in the refrigerator.
