What is a one-sentence summary of the following article?
Chafing dishes do not cook food but regulate temperature. Cook all foods, particularly raw foods, before serving them in your chafing dish. When you add it to the pan, your food should stay at the same temperature while you're serving it. Some chafing dishes may come with a thermometer to help monitor your food's temperature. If your model does not, use a food thermometer to make sure your dish remains hot. Check the food's temperature about every 25-30 minutes as long as you are serving it. Cook your food in the removable pans provided with your chafing dish. When you are ready to place them on, lower them carefully into the pan slot. Carry the food pans with oven mitts or dry cloths as you place it in the chafing dish to prevent burning your hands. Leaving your food unattended in the chafing dish can leave it damp and tasteless. Every 10-20 minutes, check on your dish and evaluate how it looks. Stir the food around with a serving spoon if it looks limp or stale. Keeping your food exposed for too long can remove the moisture from your dish. If you plan on leaving your food in the chafing dish for more than an hour without serving it, closing the lid will help your food retain moisture. Continue checking on your food periodically to keep it looking and tasting good. While your food is being served, you may not be able to keep a lid on it. Exposure to air can put it at-risk of drying out. If your food looks too dry, add more water to the bottom pan of the chafing dish. This can restore moisture to your food and help it maintain ideal flavor. How much water you add depends on how much food is in the chafing dish. Start small (1 or 2 tablespoons), adding more if your food remains dry. If unexpected situations arise, you may need to transport your chafing dish. Grasp each side of your chafing dish in an upright position to prevent spillage. Walk slowly and carefully as you move the appliance from one area to another. If you do not feel comfortable moving the entire chafing dish at once, it can be easier to move it in pieces. Carry the lid, water and food pans, and stand in an upright position as you move it elsewhere. Blow out your chafing dish's flame before you transport it anywhere.

Summary:
Heat up your food to the proper temperature before adding it to the pan. Transfer your food pans to the chafing dish. Check on and stir your food in the chafing dish periodically. Use a lid to keep the food fresh. Assess your food for signs of dryness. Keep your chafing dish in an upright position when holding it.
