Here is a copycat recipe of Starbuck's Frappucino. Very close to the original and much, much cheaper! I found this on Recipezaar. Some recipes call for pectin but I like this one because it only calls for ingredients I already have in the kitchen! Enjoy!
1/2 cup brewed espresso or coffee (chilled slightly)
1 Tablespoon sugar
1/2 cup skim milk
1 1/2 cups ice
Put all in blender and whirl to your heart's content! Yummy. Perfect for these hot days!
