Ingredients

  • 600 g – 4 cups blueberries
  • 350 g – 1 ¾ cups granulated sugar
  • 1 tbsp lemon juice

Instructions

  1. Place the blueberries, sugar, and lemon juice in a large pot. Set it over medium heat and stir gently until the sugar dissolves and the fruit begins to release its juices.

  2. Bring the mixture to a gentle boil, then let it bubble steadily for 20 to 30 minutes, stirring occasionally, until it thickens to a soft jelly consistency.
  3. Meanwhile, place a small plate in the freezer to chill for testing the jam.
  4. When the jam looks glossy and slightly thicker, remove it from the heat.
  5. Spoon a small amount onto the cold plate and leave it for a minute. Push it gently with your finger. A slight wrinkle means it’s ready. No wrinkle means it needs a few more minutes, then test again.
  6. Pour the hot jam into sterilised jars and seal with lids.

Recipe Notes

For a smoother finish, you can blend the jam with a hand blender before pouring it into sterilised jars.
