Homemade Strawberry Jam
Ingredients:
5 - cups prepared ripe strawberries (about 4lbs)
1 - 7.5 oz box (49 - gram) Sure Jell powdered
fruit pectin
1/4 - cup lemon juice
1/2 -teaspoon butter or margarine, optional
7 - cups sugar, measured into a separate bowl
canning jars, lids and rings
large canning pot
Directions:
Bring boiling-water canner, half full with water,
to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water.
Place washed jars in boiling water for 10 minutes
to sterilize them.
Pour boiling water over flat lids and rings in
saucepan off the heat. Let stand in hot water until ready to use. Drain well
before filling.
Remove the stems from the strawberries and lay
them on a large baking sheet. Using a potato masher crush strawberries
thoroughly, one layer at a time.
You can leave some chunks, but try to mash them
pretty good. Measure exactly 5 cups prepared fruit into 6- or 8-quart sauce pot
and add lemon juice.
Stir pectin into prepared fruit in sauce pot. Add
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 sugar. Return to full rolling boil and
boil. Jam reaches it's ideal set at (220 degrees). Boil the jam until it
reaches 220 degrees (use a candy thermometer). Skim off any foam with a spoon.
Ladle immediately into prepared jars, filling to
within 1/8 inch of tops. Wipe jar rims and threads with a clean cloth. Cover
with 2-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 pint size jars for 10 minutes and half
pints for 5 minutes. Using canning tongs remove jars and place upright on a
towel to cool completely. Check seals by pressing middle of lid with finger.
If the lid does not pop back then it is sealed. If the lid pops back when pressed then it is
not sealed. Either reprocess jars or store in refrigerator.
Store properly canned jam in pantry. Properly
canned items can last in your pantry for up to 1 year.
