An easy, quick recipe for tart-sweet frozen yogurt made with only 3 ingredients.
For a true frozen-yogurt consistency, this is best served straight out of the ice cream maker. It can be made in advance, but gets icy and firm the longer it is stored in the freezer. To expedite the process, make a big batch of the milk/sugar mixture and store it in the refrigerater for a few days, until ready to use.
