Do I have to add calcium water to my jam or jelly?

Pomona’s Pectin is activated by calcium, so calcium has to be present in the mixture either naturally or added by you. Since most people don’t know the calcium content of their fruit, we recommend a calcium water amount in every recipe to be sure there is calcium in the mixture. If your fruit has calcium in it naturally, you don’t need to add the calcium water.

The calcium water (1/2 teaspoon calcium powder mixed into 1/2 cup water) can be stored in the fridge for several months, and will just need to be tossed if it has any floating bits or smell or color. It can also be stored in the freezer where it will keep indefinitely, but will need to be thawed before use. We also highly recommend labeling your jar of calcium water, as it seems to be the first item tossed when cleaning the fridge/freezer . 😊

    The calcium does not fully dissolve in water. Can I use it even though it is cloudly?

      Correct. It should be fairly opaque.

    Can I use 1/4 t calcium powder in 1/4 c. water? I don’t make much jam and just waste the calcium water.

      You sure can!

    My facet water has Floride in it so do I still need to add calcium to my jam recipe

      Yes, the calcium water is still needed. Fluoride and calcium are two different elements.

    So what happens if you didn’t read instructions well and made calcium water and dumped the whole thing into juice?🤦‍♀️ Hopefully just calcium rich jam? Can I buy more calcium since I have leftover pectin?

      Hello Shannon,

      Oh darn! Not to worry, your jam should be just fine to consumer…just calcium rich like you mentioned! If you shoot us an email to info@pomonapectin.com we would be happy to send you some additional calcium powder 😊

    My tap water is softened with salt. Does that offset the need to add calcium water to my jam?

      Hello Robin,

      We believe that you will still proceed the recipe as directed. Happy jamming!

    Hey there,
    So I’m a complete idot in the kitchen and thought that your pectin was a package of gelitin. I dumped the whole thing into simmering blueberries (about one pies worth), and now is in the fridge to stiffen up. I JUST saw a little white package that said calcium on my counter. SO, that wasn’t used.
    Is my pie dangerous to eat? I’m sure the consistency will be a nightmare (as usual), but is using the whole package for a pie going to hurt our tummies??

      Oh no! We are so sorry that happened Monique! Let me just say, you are not the first to have done this, and you will not be the last.

      Your blueberry pie will probably be very well jelled, and if you can stomach the texture of it, the over-pectined pie should not have any ill effect on your tummies. 😊

    If moderately hard water (120 mg/L) is used to make calcium water, does that increase the hardness of the set in jam or marmalade? The last time I used Pomona’s Pectin I followed directions to make apple jelly (using really sour crab apples) and wound up with jelly that had a very hard set.

      We believe that would have an effect on the jelly, yes. Feel free to skip the addition of calcium water.

    So my calcium water got thrown out. Where can I buy calcium to replace what I’ve lost?

    What if I used all my calcium water up but still have more pectin to use? The recipe calls for 1/2 t. of calcium water. That’s the entire contents of the calcium water packet. But it only calls for 1 1/2 t of pectin. So there’s pectin left but no calcium water. Please advise!

      The calcium water is made up of 1/2 teaspoon calcium powder with with 1/2 cup water, then from that solution you will used the required 1 1/2 teaspoons of calcium water.
      The calcium water can be stored in the fridge for several months (will just need to be tossed if it has any floating bits or smell or color). It can also be stored in the freezer and will keep indefinitely, and will just need to be thawed before use.

          Which recipes are you trying to follow? Do they call for using Pomona’s Pectin?

    My gelato recipe calls for 1 tablespoon of “liquid pectin”. How do I convert your pectin and calcium into liquid pectin? I bought the 1.1oz box.

      Hello David,

      Thanks so much for reaching out! Pomona’s Pectin is not a direct replacement for liquid pectin, so this is our best guess at how to substitute it.

      You will need to dissolve Pomona’s Pectin into boiling water and get it to dissolve. (Bring 1/2 cup water to a boil. Place into food processor/blender. Add proper amount of Pomona’s Pectin, to make liquid pectin. Make sure to VENT LID. Blend 1-2 minuted until all the powder is dissolved. (if mixture is too thick add a small amount of additional water, juice or some of your fruit to loosen up and assist with removing from blender)

      We would guess that your will need 1/8 teaspoon of Pomona’s Pectin to replace the 1 tablespoon liquid pectin. The calcium from the milk in your gelato should be sufficient to jell the pectin.

      Best of luck and we would love to hear how it turns out!

    When I search “calcium water,” your site says that I need to add it if my fruit doesn’t have calcium. Sadly that doesn’t answer the question most of us have. In fact it begs another one, meaning there are two:
    1) How do we know the calcium content of our fruit, and
    2) Where do we get calcium water or how do we make it?
    This info would be far more helpful. I’m keen to use your product, but I won’t purchase it if I don’t know if I’ll be able to activate it.

    Would you advise, please?

      Hello Charlie,
      Every purchase of Pomona’s Pectin will come with an adequate amount of calcium powder. Each of our recipes, in the direction sheet and on our website tells you how much calcium water is needed for your jam/jelly to jell, so there is no guessing or research needed.

      Please let us know if you have any other questions. We are happy to help!
