Where possible, spread food out evenly in pans. Do not allow food to protrude above pans, since this will interfere with
steam circulation between pans in the compartment.
Always preheat compartments for satisfactory results. When time does not allow for defrosting of frozen vegetables, such
as loose-pack peas, corn, diced carrots, etc., they may be cooked at once provided just half of the suggested portions in
the cooking chart are used.
