Ingredients:
- 6 cups (approximately 1.36 kg) crushed fresh berries (strawberries, raspberries, blueberries, or a mix), thoroughly washed and hulled
- 4 cups (800g) granulated sugar
- ¾ cup (90g) instant pectin powder (such as Sure-Jell for less or no sugar needed recipes)
- ¾ cup (177ml) water
- 1 tablespoon lemon juice (optional)
Instructions:
- Gently wash and hull the berries. Crush them in a large mixing bowl using a potato masher or fork.
- Add the sugar to the crushed berries and stir thoroughly until well combined. Let the mixture stand for 10 minutes, stirring occasionally to dissolve the sugar.
- In a separate small bowl, whisk together the instant pectin powder and water until smooth.
- Pour the pectin mixture into the berry-sugar mixture. Add the lemon juice (if using). Whisk vigorously for 1 minute.
- Ladle the jam into clean freezer-safe jars, leaving ½ inch (1.25 cm) of headspace at the top. Wipe the rims of the jars clean with a damp cloth.
- Place the lids on the jars and screw on the bands until fingertip tight.
- Let the filled jars stand at room temperature for 24 hours to allow the jam to set properly.
- After 24 hours, freeze the jam for up to 1 year.
- To use, thaw the jam in the refrigerator for several hours or overnight. Once thawed, it will keep in the refrigerator for up to 3 weeks.
