Woks work in any kitchen setting, including a catering service and a hospital cafeteria. A wok adds variety to the kitchen because the pan can accommodate dishes that require frequent stirring, as the high rim prevents food from splashing out. Natural finish woks also distribute heat more evenly than a traditional frying pan and require less oil during cooking. As with frying pans, woks come in different sizes, such as 7 inch and 11 inch, to accommodate cooking volume needs. Some woks come with coating to prevent sticking, while natural finish woks have an uncoated surface for a more organic cooking experience.
