Grape Jelly

4 lbs slightly underripe concord grapes

1 cup water

sugar

Day before; wash, stem and crush grapes. Put in a large pot, add water

and bring to a boil. Boil over medium heat for 10 minutes.

Remove from heat and pour through a jelly bag, or large sieve, lined with

several layers of cheese cloth. Allow juice to drip through without pressing

grapes against side of bag or sieve. Let stand in a cool place overnight.

Next day, measure juice; return to pot. Add 3/4 cups sugar to every 1 cup

of juice. Cook over low heat, stirring until sugar is dissolved. Boil rapidly
