Black Grape Jelly

In a saucepan, place the grapes and cover with water

Bring to a boil, then reduce heat and simmer for 10-15 minutes or until the grapes are tender

Strain the mixture through a cheesecloth or fine-mesh sieve into a clean bowl, pressing on solids to extract as much juice as possible

The resulting liquid should yield approximately 6 1/2 cups of juice

Return the juice to the saucepan, add sugar and stir until dissolved

Bring the mixture to a boil over medium heat, then reduce heat to low and simmer for 10-15 minutes or until the jelly has thickened and passed the test

Remove from heat and let cool slightly

Continue cooking and testing the jelly's consistency by dipping a spoon into the liquid and letting it cool

If it's still too runny, continue cooking and testing until it reaches the desired consistency

This process takes approximately 1 hour and 15 minutes

Meanwhile, sterilize a glass jar with capacity for 5 cups and lid in boiling water, then let it air dry

Pour the jelly into the prepared jar and seal

Store in a cool place

Shelf life is approximately 5 cups or 80 tablespoons.
