Ingredients:
- 4 cups (600g) fresh strawberries, hulled and washed
- 1 tbsp (15ml) fresh lemon juice
- 1 box (1.75 oz / 50g) Sure-Jell low sugar strawberry freezer jam pectin
- 2 cups (400g) granulated sugar
Instructions:
- Crush the hulled strawberries. Use a potato masher until the berries are broken down but still contain small, visible chunks.
- Transfer the mash to a large measuring cup and remove any excess until you have exactly 3 ½ cups (830ml) of crushed fruit.
- Whisk the low sugar strawberry freezer jam pectin into a mixing bowl.
- Slowly stir in the crushed strawberries and lemon juice. Mix constantly for 2 minutes until the pectin is fully hydrated and no clumps remain.
- Pour in the sugar and stir vigorously until the sugar dissolves and the mixture becomes a thick, glossy concentrate.
- Spoon the jam into freezer safe half pint jars, leaving ¼ inch of headspace.
- Use a spatula to eliminate air pockets until the jam is packed tightly.
- Place jars in the freezer for 24 hours to allow the pectin to chemically set.
