Our grapes were ripe on the day I went into labor. Which do you think took my attention?
So, the kids (and Chester) picked.
Chester piled them into the roaster, added a cup or two of water and put it on low.
Several hours later (this is fine for up to 12 hours or so), they were all cooked out -- the only lumps remained were seeds. Then Chester strained the mixture through a pillow case into ice cream buckets and froze the juice.
Monday (three weeks later) I felt somewhat recovered and ambitious, thawed the juice, and made up 21 jars of jelly. Yummy!
