Grape Juice canning question
I used a grape juice canning recipe where it calls for a cup of sugar and a cup of cleaned wild grapes in a quart jar. Pour boiling water over to fill jar and hot water bath for 25 minutes. They sealed up just fine.
But the sugar was supposed to dissolve during processing, but all 10 jars have a big clump at the bottom of the jars, and they won't dissolve or break up.
Any suggestions? Thanks!
