Take a mango and peel off the skin with a knife (be careful!). After peeling the skin, cut the mango into whatever size pieces you want and put them in the blender, as long as you put in HALF a mango.
Place 2 cups of milk in the blender along with the mango.
Add 1/2 cup of sugar.
Blend.
Pour in a glass then add crushed ice on top (the shake is warm without the ice).
