What do you do when your recipe says it takes only five hours but you're at work for nine? Food is safe to eat if it’s kept at 135F or higher. That also happens to be the temperature of Hamilton Beach slow cookers’ WARM setting. The company’s Intellitime Slow Cookers are designed to accommodate extended cooking times, allowing you to set the number of hours you want to cook instead of recipe cooking time. (The heat cycle adjusts based on the hours programmed.) Also, keep in mind that you should never reheat food on the WARM setting. Make sure food is heated thoroughly first, and then it can be held on WARM.
