Egg Toast

Melt one tablespoon butter, add one tablespoon
flour mixed with one-half teaspoon salt
and one-eighth teaspoon pepper, and pour on
gradually one cup milk. Add the whites of
three hard-boiled eggs, finely chopped. Pour
over four slices of toasted bread, and sprinkle
the top with the yolks of three hard-boiled
eggs forced through a potato ricer or strainer.
