I use this recipe for all freezer berry jams
3 cups crushed berries *
5 cups sugar
1 package powdered pectin (Sure Jell)
1 cup cold water
Put the cleaned and stemmed berries into a large mixing bowl. Add the sugar mix well, and let stand for 20 minutes. Stir occasionally.Dissolve the Sure Jell in 1 cup cold water in a saucepan and bring to a boil. Boil one minute. Add pectin solution to the fruit and sugar mixture. Stir vigorously for two minutes. Pour the jam into clean freezer containers or canning jars, leaving 1/2" headspace. Cover the containers and let stand for 24 hours or till the jam has set and become firm. Makes about 8 half pint jars or freezer containers. Thaw overnight in the refrigerator. *DO NOT PUREE THE BERRIES. They need to be crushed or they will be too juicy
