Description

This Strawberry Freezer Jam is a deliciously sweet and easy-to-make homemade jam featuring fresh crushed strawberries combined with sugar and fruit pectin. Prepared without cooking the fruit directly, this freezer jam sets quickly in jars and offers a fresh, summery taste perfect for spreading on toast or adding to desserts. With minimal cooking focusing on activating the pectin, this recipe yields a vibrant, chunky jam that can be stored conveniently in the refrigerator or freezer.


Ingredients

Jam Ingredients

  • 2 cups crushed fresh strawberries (about 1 quart whole strawberries)
  • 4 cups granulated sugar
  • 1.75 ounce fruit pectin (we used Sure-Jell)
  • ¾ cup water


Instructions

  1. Prepare Jars: Thoroughly wash and sterilize mason jars and lids by boiling them in water or running them through a sterilization cycle in the dishwasher to ensure they are clean and safe for storing the jam.
  2. Prepare Strawberries: Rinse the strawberries and remove the stems. Slice the strawberries into halves or quarters to make crushing easier.
  3. Crush Strawberries: Using a potato masher, crush the strawberries into very small pieces, being careful not to puree them to maintain small chunks in the jam.
  4. Measure Strawberries: Precisely measure out 2 cups of the crushed strawberries, including their juice, and place them into a large mixing bowl.
  5. Mix Sugar: Add exactly 4 cups of granulated sugar to the crushed strawberries and stir well. Set this mixture aside while preparing the pectin.
  6. Prepare Pectin Mixture: In a small saucepan, stir the entire 1.75-ounce packet of fruit pectin into ¾ cup water until fully combined.
  7. Boil Pectin: Heat the pectin mixture over medium-high heat, stirring constantly. Bring it to a boil and continue stirring, maintaining the boil for one full minute to activate the pectin.
  8. Combine Mixtures: Pour the boiling pectin mixture into the large bowl with the strawberry and sugar blend. Stir thoroughly until nearly all the sugar is dissolved, leaving only a few granules visible.
  9. Jar the Jam: Ladle the mixed jam carefully into the prepared jars, leaving appropriate headspace. Secure the lids loosely at first and let the jam set for 24 hours at room temperature.
  10. Store Jam: After the 24-hour set period, tighten the jar lids completely and store the jam in the refrigerator or freezer for long-term preservation.

Notes

  • Do not puree the strawberries; a chunky texture is preferred for freezer jam.
  • Exact measurements of sugar and pectin are critical to ensure proper setting and preservation.
  • Sterilizing jars helps prevent spoilage and extends shelf life.
  • Store jam in the freezer for up to one year or refrigeration if consuming sooner.
  • Allow jam to set at room temperature before moving to cold storage to ensure proper gel formation.
