Blueberries are full of antioxidants and packed with vitamin C; healthy and delicious, we simply had to show you this recipe for blueberry jam. If you want to treat the foodie in you to new jam jars full of fruity goodness made by none other than yourself, this recipe is for you.

Recipe Ingredients

  • 800g Washed Blueberries
  • 500g Granulated Sugar
  • 1 Large Lemon – Juiced
  • 1 Vanilla Pod (Split Lengthways)


Recipe Equipment

  • 2 500ml Jam jars
  • Medium-sized, heavy-based saucepan
  • 1 Small Plate
  • Potato Masher



  1. Sterilise two jam jars (recommended: 500ml)
  2. Put a small plate in the freezer for testing purposes
  3. Add the blueberries, sugar, lemon, and vanilla to a medium-sized saucepan
  4. Choose a medium heat
  5. Use a potato masher to break up the blueberries slightly
  6. Bring to the boil before reducing to a simmer
  7. Cook for 30 minutes and then evaluate
  8. If any layers have formed at the top, discard with a spoon
  9. Place a spoonful of jam onto the plate prepared earlier
  10. Place the jam in the fridge for 2-3 minutes for optimum temperature
  11. Test its readiness by seeing if a skin has formed
  12. Place some jam on the plate and run your finger through it
  13. Apply light pressure - if the jam begins to crease, it has reached setting point
  14. To continue to test, return to heat for 5 more mins
  15. Repeat the test until you are satisfied it has reached setting point
  16. Leave your homemade blueberry jam to cool for 10 mins
  17. Ladle into the warm jars you sterilised earlier
  18. Now leave to cool entirely
  19. Once opened, use within a fortnight
  20. Unopened, you can store your jam for up to 6 months
Fresh blueberries are available in the UK when their season starts between late July and almost all of August. While eating them alone certainly has the yum factor, taking the time to make a delicious jam fares well for an ultra-special toast treat or a refreshing twist on traditional scones. Once you have opened the sealed lid on your blueberry jam, you can store the jam jars containing your home-made delights for around a fortnight in the fridge. If you want to know anything more about optimal storage to optimise your jam-making efforts, get acquainted with the experts.
