This strawberry freezer jam is the ultimate quickly preserved jam! Made with a drastically lower amount of sugar than traditional freezer jams, it’s thickened with chia seeds with no loss of flavor. The true essence of the strawberries shines through and will be perfect to use at a later time.
In a large stock pot, combine the hulled and washed strawberries, sugar, and lemon juice. Use a potato masher to crush the berries slightly. Place the stock pot over medium heat and bring to boil. Once boiling, reduce the heat to a simmer and cook for 5 minutes.
Once the jam has cooked for 5 minutes and the sugar is dissolved, remove the jam from the heat. Add the chia seeds and stir. Allow the chia seeds to thicken for 5 minutes and stir again. Check the consistency of the jam by placing a small amount on a frozen plate. As the jam cools, it will show the true consistency. Add more chia seeds, one tablespoon at a time, and allow them to thicken for 5 minutes until the desired consistency is achieved.
Pour into airtight containers, label, and freeze the jam. The jam will freeze solid but will thaw in the refrigerator overnight. If kept in the refrigerator, the jam will last 2-3 weeks.
Allow the chia seeds to thicken for at least five minutes. You can always add more chia seeds to continue making the jam thicker. Simply add more seeds and allow the new amount to thicken for five minutes as well.
Frozen strawberries can be used in place of fresh strawberries. If you don’t have time to make jam while strawberries are in season, quickly freeze some and make this later. To prepare the jam using frozen strawberries, let them thaw to room temperature before cooking.
To test the consistency of the jam, keep a small plate in the freezer and pour a small amount of jam on it. The jam will quickly chill and show its consistency. Instantly, you’ll know whether you need to add more chia seeds.
