Purple Cow Shake

Sorry this picture isn't very clear but I didn't have anything to put this shake in to take a nice picture.  Just trust me that it's tasty.  My kids love it and it's so easy to make.

1 6 oz. can frozen grape juice concentrate (I use Welch's grape juice cocktail)
1 cup milk
2 cups vanilla ice cream

Pour grape juice concentrate and milk into blender container; add ice cream.  Cover and blend on high speed 30 seconds.  Makes 3-4 shakes.

I have used 100% grape juice but it is too grapey so that is why I use the grape juice cocktail instead.
