• 4 cups bottled Concord grape juice
• 7 cups white sugar
• 2 pouches Certo liquid

Sterilize jars and lids.

Measure juice into a large saucepan, add the exact amount of sugar shown above. Place over high heat and bring to a rolling boil, stirring constantly. Immediately stir in Certo and continue to stir over high heat for one minute.

Remove from heat and skim off any foam with a metal spoon. Skim and stir for 5 minutes, making sure mixture is uniformly thick.
