Chop cold boiled potatoes, put them in a baking dish, pour over them a
cupful of white sauce nicely seasoned, sprinkle with a tablespoonful of
grated Parmesan cheese or Edam cheese grated, one tablespoonful of bread
crumbs, and dot all over with tiny bits of butter. Put in a quick oven
for a few minutes to brown. Do not leave it in too long, or it will
become dry.
