Easy strawberry jam recipe with big strawberry flavor, sweetened with sugar or honey.

Ingredients

Units Scale
  • 4 cups mashed strawberries (you will need about 8 cups fresh berries)
  • 12 cups white sugar – or – 1/2 to 1 cup honey
  • 2 teaspoons Pomona’s pectin
  • 2 teaspoons calcium water (included in the Pomona’s Pectin box pectin box)

Instructions

  1. Sterilize jars and prepare lids and rings. Keep jars warm. Fill water bath canner with hot water. Bring to boil while prepping the jam.
  2. Prepare fruit by mashing with a pastry blender or potato masher, or gently chopping in a blender.
  3. Add proper amount of calcium water from jar into pan; stir well. (Instructions for making the calcium water are in the box and in the video below.)
  4. Measure sugar or cold/room temperature honey into separate bowl. Thoroughly mix proper amount of pectin powder into the honey or sugar. Always premix your sweetener and your pectin powder to prevent clumping.
  5. Bring fruit to boil. Add pectin-honey-sugar mix; stir vigorously 1-2 minutes while cooking to dissolve pectin. Return to boil and remove from heat. Letting the jam cool just slightly before placing in jars will help keep the fruit mixed in the jars instead of all floating at the top.
  6. Fill jars to 1/4″ of top. Wipe rims clean. Screw on 2 -piece lids. Put filled jars in boiling water to cover. Boil 10 minutes (add 1 minute more for every 1,000 feet above sea level). Remove from water. Let jars cool. Check seals – lids should be sucked down. Lasts about 3 weeks once opened, at least a year in the pantry unopened.
