Cut your peaches in small pieces and put them in your blender with half a cup of water
Blend till you get a sort of purée
Put the "purée" in a separate container
Blend water with as much brown sugar as you want
Pour the purée into the water with sugar and squeeze two lemons inside the blender
Sorry for the blurry picture! Btw,you can skip this step.
You now have a yummy refreshing drink!
