Do I need to preheat the oven before broiling?

Preheating is suggested when searing rare steaks; preheat by setting the controls to BROIL for 3-4 minutes or until the element turns red-hot. You can select either high or low broil based on the type of food being prepared. Broiling times vary depending on distance from the element, meat thickness, fat content, and desired doneness.
