Abstract: The invention provides a cooking pan with a handle that extends both outwardly and downwardly from the pan bowl to which it is connected. A pouring lip of the pan bowl is displaced substantially 180° from the handle. The pouring action is therefore a forward pouring action as opposed to the side pouring action of conventional saucepans. This has safety implications because the liquid (which may be hot or even boiling) is poured directly away from the user in a manner not possible with the conventional side position of a pouring lip. Because of the shape of the handle and the angle that it forms with the vertical, the pan is comfortable to hold and to use even with this unconventional position of pouring lip.
