I slice my orchard peaches and fill freezer bags or recycled yogurt containers at the peak of the season. Then when we want milkshakes, I chunk off the amount I need.
2-Cap the blender, and while running, add frozen peaches through the cap opening, until the milkshake is thick. This takes approximately 2 cups peaches.
3-Add a little shake of stevia extract to sweeten, if desired.
