Jacques Torres, the host of "Nailed It!" and a renowned pastry chef, has shared a tip on how to prevent burning yourself while handling hot food. He advises keeping a bowl of cold water on the counter when dealing with hot ingredients, especially when working with fried pastries that require rolling in another ingredient while still warm. By periodically dipping your fingers in cold water during the cooking or baking process, you can help prevent mild burns and protect your skin. However, it's important to note that this method is not foolproof and won't work for more severe burns or handling extremely hot surfaces.
