Fill a 1 Quart Canning Jar 1/2 of the way full of washed concord grapes picked off your vine. Stems, seeds, maybe a leaf or two included! Add 1/2 C. Sugar. Fill jar with boiling water and process in a hot water bath for 30 minutes. When you serve, pour chilled contents through a strainer and enjoy.
(I have not done this yet, but my friend Megan shared this FUN, EASY, UNUSUAL recipe with me and the best part...It's delicious! I was able to taste the finished product. I can't wait to try it this summer with my own grapes. I think I'll also try making some sugar free for P.J. (using Agave Nectar.) Last summer, I was at a loss as to what to do with them, because I didn't have the proper juicing equipment.... UPDATE 2012: Love this! I have a lot more of my sweet, seedless, green grapes than the concord. For the sweet green grapes, I decrease the sugar to 1/3 C. I bottled over 36 quarts of juice this year. When we serve it, I usually mix equal parts juice to Fresca Soda. mmmmm...)
