I had completely forgotten this icy drink until a hot day earlier this month. I adjusted the measurements a little, and my family was delighted with the result!
Orange Julius (Yield: 4 large or 5 medium servings)
4 T. powdered sugar
2 T. granulated sugar
1 tsp. vanilla extract
2 cups orange juice
1 cup milk
Measure the ingredients into a blender/smoothie jar in the order listed. Add a couple of handfuls of ice--about two cups. (You want to leave a couple of inches of space at the top because it will get foamy.) Blend till ice is crushed and thoroughly incorporated. Pour into tumblers and serve immediately.
