Frozen Yogurt

I like a good frozen yogurt as much as I do a good ice cream, and luckily I recently found, and slightly modified, a good recipe. You need some kind of ice cream maker to make this, but it generally takes much less time than any ice cream recipe I've made, either in prep time, or freezing.
This is not a low fat recipe. Substituting in low-fat ingredients will cause large ice crystals to form, which are poor for the texture of the frozen yogurt.
Enjoy!

Frozen Vanilla Yogurt

3 Cups Unflavored Whole Milk Yogurt
1 Cup Half and Half
2/3 Cup Granulated Sugar
1 Tablespoon Vanilla Extract (or put 2 Tablespoons Vanilla Sugar in the measuring cup before measuring out the sugar),

Mix all ingredients together and follow the instructions for your ice cream maker to freeze to a creamy texture.
