Course Breakfast, Dessert, Snack
Cuisine American
Servings 8 cups

Ingredients
  

  • 5 cups prepared fruit buy about 2 qt. fully ripe strawberries
  • 1 box SURE-JELL Fruit Pectin
  • 1/2 tsp. butter or margarine
  • 7 cups sugar measured into separate bowl

Instructions
 

  • Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
  • Stem and crush strawberries thoroughly, one layer at a time. Measure exactly 5 cups prepared fruit into 6- or 8-qt. saucepot.
  • Stir pectin into fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly.
  • Stir in sugar. Return to full rolling boil and boil exactly 1 min., stirring constantly. 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 elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if needed.) Cover; bring water to gentle boil. Process 10 minutes (adjust for altitude*).
  • Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middle of lids with finger. (If lids spring back, lids are 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 jam.
