Easy Strawberry Jam

Strawberry Jam

3 3/4 cups crushed strawberries
1/4 cup lemon juice
7 cups sugar
1 package Certo Liquid Pectin

Preheat the oven to 225 degrees F.  Wash and rinse 8 one cup jam jars. Drain the jars of excess water and place them upright on a cookie sheet.  Place the cookie sheet in the 225 degree oven for a minimum of 10 minutes. This will sterilize the jars. You can keep the jars in the oven until the jam is ready to be poured into the jars.

Place the washed lids and seals in a medium saucepan filled with water along with a set of metal tongs, which will be used to place the lids on the jars.  Boil them for at least ten minutes.

Use a potato masher to crush the berries, one layer at a time. With liquid measuring cup measure out the 3 3/4 cups of berries. Pour the berries into a large saucepan. Add the sugar and lemon juice. Do not reduce the amount of sugar, the full amount must be used for the jam to set. Turn the heat to high and bring to a full rolling boil. Let boil for one full minute.

Remove from heat and stir in the package of liquid pectin. Skim the foam from the top with a large flat metal spoon and stir the jam for 5 minutes to distribute the fruit evenly.

Remove the cookie sheet with the jam jars from the oven. With a small ladle, fill the jars with jam, leaving 1/4 inch of space from the rim. Using the tongs (cover your hand as the tong handle may be hot from being in the boiling water) remove the seals from the water, one at a time. Shake excess water from the seal and place on the jar. Then, still using the tongs, remove the rings. Again, shake off excess water and place the rings over the seals and tighten firmly.

The jam will take about 12-24 hours to set. The seals should pull down as the jars cool and you may hear clicking sounds as the seals form. If the fruit has settled to the top, turn the jars over to redistribute as they cool.

Jars may be kept unopened up to one year on the shelf.
