A cloche or plate cover is a good item to have in a pinch. It is great for serving food outdoors. It will not only keep out bugs, sand and dust, it will also keep out bacteria much like a sneeze guard, and will also benefit you by retaining the heat in the plate. When choosing a cloche, the most important factor is the size of the plate it will be covering. Make sure it will cover the entire opening. Another key factor is the material type. A metal cloche is durable and practical, while a porcelain cloche is more breakable but also more attractive. Whether you are running a fine-dining establishment, an outdoor catering operation, or simply putting on an outdoor house party, plate covers or cloches will give your plates and bowls a sense of refinement.
