There are two main methods for warming dinner plates. The longer but safer method involves submerging the clean plates in boiling hot water for five minutes before removing them and drying them with a dishtowel, followed by a wipe down with a paper towel to guarantee its residue free. Otherwise, stack your plates and place them into an oven preheated to 160°F. Let them bake for ten to fifteen minutes or until they reach approximately 175°F. A warmer draw works even better for heating up stacks of plates. Lastly, warm dinner plates in the microwave by microwaving them one by one with a glass of water on top for two minutes each.
