Special utensils are made for use on kerosene, gas, and electric stoves, which are so shaped as to make it possible to cook two or three foods in as many utensils at one time over one burner.

A pressure cooker cooks food in from one-third to one-fourth the usual length of time. Although its initial cost is somewhat high, the amount of fuel that may be saved by its use during a year greatly decreases this cost.

A steamer in which several kinds of food can be cooked at the same time over one burner saves fuel if the meal is planned to that end.
