This is a wonderful change from the normal cakes, cookies, and pies that are usually seen at a family dinner or other group functions. Because it consists of fresh grapes, it has an added health benefit plus it is very delicious. Everyone is surprised when they taste it! You can adjust the amount of grapes to suit your needs - just be sure to adjust the other ingredients to correspond to the amount of grapes you are using. You can also adjust this recipe to do a lighter version which is just as delicious, (light or fat free sour cream and Splenda).
