Certo Red Raspberry Freezer Jam Recipes

Steps:

• 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 jars well before filling.
• Crush raspberries thoroughly, one layer at a time. (Press half of pulp through a sieve to remove some of the seeds, if desired.) Measure exactly 4 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir in sugar. 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 pectin. 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 necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

• Bring raspberries to a boil in a very large pot. Cook for 4 minutes. Add sugar and lemon juice; stir well. Bring back to a boil, stirring constantly. Cook for another 4 minutes.
• Remove pot from heat and pour jam into sterilized jars, leaving 1/4-inch of space at the top. Seal and transfer jars into a boiling water bath. Make sure jars are covered with at least 1 inch of water; let sit for 5 minutes. Lift jars and let them cool in a draft-free place without touching, 8 hours to overnight.

Steps:
