  • 5 cups crushed strawberries (about 3-4 lbs fresh strawberries)

  • 7 cups granulated sugar

  • 1 package (1.75 oz) powdered pectin

  • 1/4 cup lemon juice (fresh or bottled)


  • Water bath canner

  • Canning jars (pint or half-pint)

  • Lids and bands

  • Jar lifter

  • Lid lifter

  • Funnel

  • Large pot

  • Ladle

  • Potato masher

  • Measuring cups

  • Kitchen towels


  1. Prepare Your Equipment

    • Sterilize your canning jars: Wash them with warm soapy water, rinse well, and place them in a water bath canner or large pot. Cover with water and bring to a simmer (not a boil) until ready to use.

    • Prepare the lids and bands: Follow the manufacturer's instructions, usually involving simmering (not boiling) the lids in hot water.

  2. Prepare the Strawberries

    • Wash the strawberries thoroughly under cold running water.

    • Hull the strawberries by removing the green caps and stems.

    • Crush the strawberries using a potato masher or a food processor, being careful not to puree them completely – you want some chunks for texture.

  3. Cook the Jam

    • In a large pot, combine the crushed strawberries, lemon juice, and powdered pectin. Stir well.

    • Bring the mixture to a full rolling boil over high heat, stirring constantly.

    • Add the sugar all at once and return to a full rolling boil. Boil hard for 1 minute, stirring constantly.

    • Remove from heat and skim off any foam with a metal spoon.

  4. Fill the Jars

    • Using a funnel, ladle the hot jam into sterilized jars, leaving 1/4-inch headspace at the top.

    • Wipe the rims of the jars with a clean, damp cloth to remove any residue.

    • Place the lids on the jars and screw on the bands until fingertip tight.

  5. Process the Jars

    • Place the filled jars into the water bath canner using a jar lifter. Ensure the jars are covered by at least 1-2 inches of water.

    • Bring the water to a rolling boil and process the jars for 10 minutes. If you live at an altitude above 1,000 feet, adjust the processing time according to the altitude adjustment chart provided by the FDA.

  6. Cool and Store

    • After processing, carefully remove the jars from the canner and place them on a kitchen towel. Allow them to cool undisturbed for 12-24 hours.

    • Check the seals: The lids should not flex up and down when the center is pressed. If any jars have not sealed properly, refrigerate them and use within a few weeks.

    • Label the jars with the date and store them in a cool, dark place. Properly sealed jars can be stored for up to one year.
