I make soft serve "ice cream" using nothing more than fresh fruit and water.

Use bananas as a base for any flavored "ice cream."

3 bananas, sliced
3 handfuls of blueberries

Place in freezer on a tray/plate 1-2 hours.
Put frozen fruit in a blender with just enough water to mix things up.

Makes approximately 1 pint of "ice cream."

I have also used mangos or strawberries instead of blueberries. I may even try it with a persimmon tomorrow! Be creative! If you are having a cookout this can be made up a day or two in advanced, placed in small containers and kept in the freezer until you need it.

I haven't tried it in cones but because there is no fat in this "ice cream" it melts pretty fast. I would think small bowls would keep things from becoming too messy.
