Blueberry-Raspberry Jam (Doubleberry)
 
1 pint blueberries
1 quart red raspberries
7 cups sugar
2 pouches liquid fruit pectin (Certo)
 
Crush berries; measure 4 cups (if necessary, add water to make full
amount).
 
Add sugar, mix well.  Heat to full rolling boil; boil hard 1 minute,
stirring constantly.  Remove from heat; stir in pectin; skim.
 
Ladle into clean, hot half-pint jars, seal and process in a boiling
waterbath for 5 minutes.
 
Notes: This is an old recipe.  Current instructions for using
Certo have you boiling the mixture for one minute after the addition
of the liquid pectin.  I think I would.
