My Favorite Strawberry Jam
4 cups prepared strawberries
4 cups granulated sugar
2 tablespoons lemon juice
Wash, hull and slice strawberries, then measure into a large saucepan. Add cups of sugar. Heat and boil hard for 5 minutes, stirring constantly. Add lemon juice and the remaining 2 cups of sugar. Bring to a boil and boil hard, stirring constantly, until ready to jell.* Pour into shallow dish and stir occasionally while cooling. Let stand overnight to plump fruit. Pack cold in sterilized jars and seal. Makes 2 pints.
*Jell test: Dip a clean metal spoon in boiling jam; hold up edgewise. When 2 heavy drops form and slide together at edge of spoon, jam is ready to jell. This takes from 2 to 20 minutes, depending on pectin in fruit.
