Use fully ripe fruit for flavor and color. Need three quarts of whole fruit. Wash and stem berries. Crush or mash thoroughly and heat to a boil. Pour hot fruit into a jelly bag and extract juice from berries. Place 3 cups of juice in a 6-8 quart saucepan, add 1/2 cup lemon juice. Stir in 1 package pectin (Jell- Well), stir until dissolved. Place over high heat, bring to a full rolling boil, stirring constantly to prevent scorching. Add 4 1/2 cups pre-measured sugar, mix well. Bring back to full rolling boil and boil exactly two minutes. Remove from heat and skim if necessary. Pour into glasses and seal while hot.
