Bread for toasting should as a rule be 48 hours or more old. Cut the
desired number of slices, making each about 1/4 to 1/2 inch thick. Place
the slices on a toaster over a bed of clear coals or on a broiler under
a slow gas flame. Turn the bread frequently until it assumes an even
light brown on both sides. Remove from the heat, spread each slice with
butter, and serve while hot and crisp.
