Total Time:
45 mins
about 10 cups (about 10 half-pints)


  • 3 quart fresh strawberries, hulled

  • 1 1.75 ounce package regular powdered fruit pectin

  • ½ teaspoon butter

  • 7 cup sugar


  1. Place 1 cup of berries in an 8-quart heavy pot. Crush berries. Continue adding berries and crushing until you have 5 cups crushed berries. Stir in pectin and butter. Heat on high, stirring constantly, until mixture comes to a full rolling boil. Add sugar all at once. Return to boiling; boil 1 minute, stirring constantly. Remove from heat; skim off foam with a metal spoon.

  2. Ladle at once into hot, sterilized half-pint canning jars, leaving a 1/4-inch headspace. Wipe jar rims; adjust lids. Process in a boiling-water canner for 5 minutes (start timing when water returns to boil). Remove jars; cool on racks.


Jam may need to stand for 1 to 2 weeks after canning to become fully set.


If your fruit separates from the liquid in the jars, invert the sealed jars once or twice a day. Continue inverting until fruit is well distributed.
