Here's the familiar drill: Puree the fruit (in this case raspberries) with a bit of sugar or sweetener of choice in a food processor or blender. That's the foundation of any number of fruit-based juices or smoothies. Then add some other liquid for extra flavor, such as the freshly brewed mint tea in this recipe. Stir in a handful of fresh mint leaves (basil would also work here) and ice, and refreshment is served.
