Blueberry Pie Filling Made From Apple Juice Concentrate

Just this morning I made the best blueberry pie filling from apple juice concentrate.  I had no sugar and had read that you could use apple juice concentrate as a substitute for sugar in some recipes, so I decided to give it a try.  I added 1/4 cup of apple juice concentrate to a pan on the stove under low heat and then added about 2 tbs. of corn starch to thicken it.  It made a paste and then I added about 2 cups of frozen blueberries along with a little water and stirred it with a whisk until it reached the desired constancy.  It was absolutely delicious!  I plan on trying this also with my frozen diced peaches and my frozen whole strawberries.  The possibilities are now endless!
