Both rice warmers, and insulated sushi pots, are designed to keep cooked rice warm and moist until ready to be served at your buffet table or behind the counter. Shop for rice warmers that are either insulated, requiring no power, or electric. Insulated sushi pots allow rice to maintain a warm temperature that diminishes over time, while electric rice warmers are able to maintain a warm, consistent temperature throughout the day. Choose the one that best suits your commercial kitchen requirements.
