The second type of detector is the photoelectric smoke alarm, which uses a light beam to detect the presence of smoke. According to UL, these alarm types are more effective at sounding when a fire originates from a smoldering source, like a lit cigarette that falls into a couch cushion.
Fill a pot with 2 to 3 inches of water. Set a steamer basket on top so the basket sits above the water inside. Bring the water to a boil over high heat. Lay the baby broccoli in the steamer basket and place the lid on top. Steam the baby broccoli for 2 to 3 minutes, or until the stalks and florets brighten in color and become tender. Serve warm. Wash and trim the stalks.
Place into an oven preheated to 400 to 450 degrees Fahrenheit. Allow to cook for 15 to 30 minutes, depending on the temperature and size of the broccoli pieces. You may want to stir the broccoli around on the tray about half-way through the roasting process to facilitate even cooking.
