# Preparing the bananamilk by a blender is advised generally. But it can not be possible every time.
# Put the banana onto a flat plate, add granulated sugar onto it.
# Mash the banana by a fork to get its puree.
# Put the cold milk into a deep bowl, add the sugared banana puree into the milk.
# Whisk it until the milk bubbles by a beater.
# Fill it into a cup, and drink in a short time.
Note: For preparing strawberry milk; you should use 6 medium strawberries, 2 tbsp granulated sugar and 1 cup milk by the same method.
