Grape Jelly

3-3/4 lb Concord or Coronation grapes
1 Pkg (57 g) fruit pectin crystals
5 cups Granulated sugar

1. Rinse grapes thoroughly; drain well. Remove enough from stems to yield 10 cups, discarding any wrinkled or bruised grapes.

Let drip, without squeezing bag, for about 2 hours or until juice measures 4 cups, or place cooked grapes in colander-lined with triple thickness of damp cheesecloth. Bring up sides; tie top with string to form bag. Tie bag with string to cupboard handle or support bar over large measuring cup or bowl. Let drip, without squeezing bag, for about 2 hours or until juice measures 4 cups.

6. In large clean pot, bring juice and pectin to boil. Stir in sugar; bring to full rolling boil, stirring constantly with wooden spoon. Boil vigorously, stirring, for 1 minute. Remove from heat. Skim off any foam. Pour into seven 1-cup (250 mL) hot sterilized canning jars, leaving 1/4-inch (5 mm) headspace. Seal and process in boiling water bath for 5 minutes. Let cool on rack.
