Instructions
 

  • Prepare fruit by removing and discarding strawberry stems. Crush fruit.
  • Use dry measuring cup to measure exact amount of prepared fruit into the sauce pan.
  • Measure the exact amount of sugar into large bowl. (Do not reduce sugar in recipe since that will result in set failures.)
  • Combine 1/4 cup sugar from measured about and 1 package Sure Jell for Less or No Sugar Needed Premium Fruit Pectin in small bowl. Stir into fruit. Add 1/2 tsp butter to reduce foaming, if desired.
  • Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly.
  • Stir in remaining sugar. Return to full rolling boil and boil exactly 1 minute, stirring contantly. Remove from heat. Skim off any foam with metal spoon.
  • Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly.
  • Place jars on eleveated rack in canner. Lower rack into canner. "Water must cover jars by 1-2 inches. Add boiling wter, if needed.) Cover; bring water to gentle boil. Process for 10 minutes, adjusting processing time for altitude, if necessary.*
  • Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing centers of lids with finger. If lid springs back, lid is not sealed and refrigeration is necessary.
  • Let prepared jars stand at room temperature for 24 hours. Store unopened jams and jellies in a cool, dry, dark place for up to 1 year. Refrigerate open jams and jellies for up to 3 weeks.
