Instructions

1

In a wide bowl, crush strawberries in batches until you have 4 cups of mashed berries.
2

In a heavy-bottomed saucepan, mix together the strawberries, sugar and lemon juice.
3

Stir over low heat. Increase heat to high when the sugar is dissolved. Bring the mixture to a full rolling boil. Continue to boil, stirring often until the mixture reaches 220 degrees F on a candy thermometer's readout.
4

Pour the strawberry mixture into sterile jars, leaving 1/4- to 1/2-inch head space, and seal. Process the jars in a water bath for 10 minutes. If the jam is going to be eaten right away, refrigerate the jam and don't bother with processing.
