Canning Wild Strawberry Jam

Wild Strawberry Jam

This quick and easy recipe for wild strawberry jam preserves those first fruits of summer for winter enjoyment.  Canning this jam is optional, but if you put it in the refrigerator be sure to enjoy it within a few weeks.


  • 1 1/2 cups wild strawberries about 100 grams
  • 2 tbsp water or juice
  • 3/4 cups sugar
  • 1/4 tsp calcium water
  • 1/4 tsp Pomona's pectin powder


  1. Remove the stems from the wild strawberries and add them to a small saucepan.  Add 2 tbsp of water of juice to help prevent the strawberries from scorching before they release their juice.

  2. Bring the strawberries to a simmer, and cook on low for about 5 minutes.  The berries should release their juice.  Add the calcium water from the Pomona's pectin kit.  This is necessary to activate the powdered pectin.

  3. Mix 1/4 tsp Pomona's pectin powder into the sugar.  Feel free to reduce the amount of sugar used, but this recipe requires at least 2 tbsp of sugar to mix with the pectin to prevent clumping.

  4. Add the sugar and pectin mixture into the simmering strawberries and stir to incorporate.  Simmer for an additional minute to activate the pectin.

  5. Pour the jam into a sterilized jar, and either store in the refrigerator or process in a water bath canner for 10 minutes.  If canning, be sure to leave 1/4 inch of headspace.
