This is a traditional Shabbat hot plate, sometimes called a 'blech'. It's used in Jewish households to keep food warm from Friday night until Saturday afternoon without violating the rules about cooking on the Sabbath. The medium size has a top cooking surface of about 21.5 by 16.75 inches, giving you plenty of room for a couple pots or a large tray. It's made with an enamel coating, which is durable and easy to wipe clean. The handles are plastic so they stay cool to the touch. It plugs into a standard 120V outlet and runs at 400 watts. Important things to know: The temperature is not adjustable – it just gets hot and stays at one setting. Also, it tends to have a hotter spot right in the center, so you might want to put your main dish there and things that need less heat around the edges. A simple, reliable appliance for keeping your cholent, kugel, or other Shabbat dishes warm and ready to serve.
