Recipe notes

  • If using frozen blueberries, measure before thawing. Then thaw them either on the counter or in the microwave (zap from frozen for 4 to 5 minutes.) Don’t drain any juice off; mash that back into the berries.
  • Mash the fruit by hand for best results. Using a machine will damage the natural pectin in the fruit.
  • Pomona pectin comes with a small pouch of powdered calcium for you to mix with water to make calcium water.
  • The pectin powder will clump if you just mix it straight into the fruit; that’s why you mix it with something first.

    Was curious how long I could keep this in the fridge if I didn’t want to “can” it. Also, could I put it in the freezer to keep?

      If you make it full sugar, it might keep quite a while in the fridge. Sugar-free or low-sugar, probably it would be attacked by mould in 4 to 6 weeks.

      Freezing would be fine.
