If you've ever dealt with a faulty turntable, you've likely experienced the consequences of a microwave's uneven cooking process. That's why it's a good idea to clean your microwave regularly, removing the turntable in the process so you can clear out debris. Luckily, the easiest way to keep your microwave clean is already in your kitchen. In that case, be sure to manually rotate the dish a few times throughout the cooking process. This is also the technique for cooking with a broken microwave turntable, but given the dramatic reduction in reheating quality, you may be better off just using the oven — after all, some believe there's simply no need for a microwave anymore.
