Bechamel sauce: Put butter in a pan and melt. Add flour and stir it quick and mix well. At first it makes bubbles and the surface starts to inflate. Once it flatters, turn off the heat. Then stir it well to cool off and put it aside. Put the milk in the same pan and warm it (60C), and turn off the heat. Add the roux and mix well. Then turn on the heat and add nutmeg and stir well until it becomes solid.
