I made this completely by accident, and i love it! I use Yoplait thick and creamy yougurt, i think it gives the drink the best texture, and I also use the condensed frozen juice, welches white grape is the best, but apple also works, depends on how sweet you like it. I also found substituting 1 Delmonte Fruit chiller in polar raspberry tastes better to me than the frozen berries themselves. To each his own. For a healthier smoothie use light yougurt, no sugar added juice, and skim milk.
