The Best Strawberry Freezer Jam

About 3 pints of jam


  • 1 box of Pomona's Pectin
  • 4-5 cups pureed or crushed strawberries, about 2 1/2 to 3 lbs of strawberries (crush or puree to desired consistency, I like the mixture fairly smooth)
  • 1 1/2 cups granulated sugar (or honey, see note)
  • 2 tbsp fresh lemon juice
  • 3/4 cups boiling water


  1. Take out the small white packet of calcium powder and measure 1/2 teaspoon into a jar or container with a lid. Pour in 1/2 cup water. Shake well; set aside. NOTE: if only making a single batch, you can measure out 1/4 teaspoon calcium powder with 1/4 cup water (and the rest of the calcium powder can be stored for later use).
  2. Add the sugar and lemon juice to the strawberries and stir well.
  3. In a blender, combine the boiling water and 1 tablespoon of pectin (in the large white packet). Process until smooth.
  4. Add the warm pectin mixture to the strawberries and mix to combine. The mixture will start to jell and thicken.
  5. Shake the calcium water to recombine and measure out 4 teaspoons; add to the jam. Stir well. (Extra calcium water can be stored in the refrigerator for months.)
  6. Portion the jam into containers, leaving 1/2-inch headspace. Seal with a lid. Store in the freezer (for up to a year) or in the refrigerator (for several weeks).


This recipe has only been tested and made using Pomona’s Pectin; other brands of pectin will not work the same in this recipe. I’ve never made the jam with all honey (although you can); but half sugar/half honey is delicious. And speaking of sweetener, you can cut the sugar down even more if you like, the minimum being 3/4 cup sugar or 1/2 cup honey. Following the recipe below, you’ll have leftover pectin and calcium powder, simply fold down the tops of the packet or place in a small bag and store it in the Pomona’s box to use later. It won’t spoil. One box of Pomona’s Pectin will make three batches of the recipe below (so about 8-9 pints of jam, depending on amount of sweetener used). This recipe can be doubled. I use my food processor to puree the strawberries and it makes adding/mixing in the pectin and calcium water simple, too.
