How To Make Patty For Burger. Shape the patties around pepperoni and provolone or mozzarella. Press each mound gently in the center with the palm of one hand, while the other hand cups the beef and helps shape it into a circle.
The higher the fat content of the meat, the more hamburgers shrink as they cook. Add ground beef to a large bowl. Use your thumb to press an indentation into the center of each patty.
Start with a baking sheet lined with parchment paper.
Now put an individual portion into the burger press.
In a frying pan, heat the olive oil over medium heat and sauté the chopped onion until it becomes translucent. Form a ball, then flatten the burgers into disc. Add ground beef to a large bowl.
