I make my own yogurt a lot during the summer. We love to have smoothies, and yogurt is great in them. Add a bit more sugar and make Popsicles with them.
Here's a bare bones smoothie recipe:
1/2 cup yogurt
1/2 tea vanilla
1/4 cup sugar
2 cups frozen fruit (blueberries, strawberries, banana, etc. If fruit is fresh, add 4-6 ice cubes)
1 1/2 cups milk
I don't really use recipes to make these, I just stick stuff in the blender. So feel free to make your own changes. Recipes are just a springboard, after all.
