Most people think that the only way to get a hamburger to hold its shape is by using a bun. However, there are other ways to do this as well. One way is to use a ring mold. This will help keep the burger together and prevent it from falling apart. Another way is to use toothpicks or skewers. This method works well if you are cooking for a large group of people and need to make sure that the burgers stay together. Finally, you can also wrap the burger in foil or wax paper before cooking it. This will help to keep the burger's shape while it cooks
