*4 pounds ripe concord grapes
*1 (1.75 ounce) box of fruit pectin
*1/2 teaspoon butter
*7 cups granulated sugar
~Wash grapes & drain.
~Put grapes into a large saucepan & cook over medium heat until grapes are softened.
~Place about 2 cups of grapes into a Jelly Strainer or layered cheesecloth over a bowl.
~Keep doing this until you have 5 cups of grape juice (you can add unsweetened pure grape juice if needed)
~Bring grape juice to a boil, over medium heat.
~Cover and simmer for 10 minutes.
~Add fruit pectin to juice & mix well.
~Turn heat up to high heat, and bring to a full rolling boil for 1 1/2 minutes, stirring constantly.
~Stir in sugar all at one time.
~Bring back to full rolling boil for 1 to 1 1/2 minutes, stirring constantly.
~Remove from heat.
~Skim off any foam.
~Pour hot jelly into sterile jars, leaving 1/2 inch headspace.
~Wipe tops of jars making sure any jam residue in removed.
~Process in a hot water bath for 10 minutes.
~Remove from water bath and let cool.
~Listen for the ping sound. This means that your jelly has sealed.
~Let sit for 24 hours before storing in a cool, dry space.
**If you feel a bubble in the lid after it's cooled, this means it did not seal. Either start the water bath again, with a new lid, or just store in the refrigerator.
