I also find it helps to remove the pot from the heat, then blend in the milk
a little at a time, stirring constantly. When all the milk is blended,
then put the pot back on the heat and stir constantly just until it thickens
and just comes to the boil (to remove the flour taste), reduce the heat, add
the grated cheese and stir well again until cheese is melted.
