• 1.
• Place the berries in a large, heavy stockpot and place them over medium heat.

• Remove them from the heat and put them through a food mill, to extract the juice.
• You should have about 3 pounds of juice.

• 3.
• Remove from the heat and seal according to the jar manufacturer's instructions.
