In New Orleans, French toast is prepared with French bread. The recipe is called pain perdu, or "lost bread" in French.
Nutmeg is the kernel of a fruit that resembles an apricot. The fruit grows on a tropical evergreen tree. The kernel is covered with a lacy coating, which is removed and ground into mace.
Covering the surface of the baking dish with bread is critical to the success of this recipe. Since loaves of French bread vary in size and diameter, you may need one or two slices more or less than called for to cover the dish.
