Buy an electric baking pan and see if you can achieve the desired effect. . . It is not recommended that you engage in mobile vendors. . . First, you can't fix it. . . If you don't have a fixed income, this way doesn't guarantee that you will feel insecure. . . Second, it is unsanitary. . . I suggest you advertise. . . Meals for several people or units. . . Or you can order Mito takeout. . . In short, my suggestion is that you should have a fixed place and a fixed source of customers. . It's safer this way! Hope to adopt?
