The Hoan hamburger stuffer creates an excellent, juicy stuffed hamburger that seals and contains all the fillings very well. It can be used to make regular beef hamburgers, or step it up a bit with gourmet burgers. You can you easily stuff a burger with your favorite cheese, vegetable, or filling. One of the great features of this product is that once the patty has been pressed, you slide the ring from the base, and the burger easily and conveniently drops out the bottom. In addition to the outstanding job it does with making a great stuffed burger, it also accomplishes the secondary task of making a perfectly round and packed hamburger patty if one is in the mood for a regular burger. Its dual function makes this the go-to hamburger stuffer!
