There are a few ways to make smash burgers without a bacon press. The first is to use a heavy-duty spatula. The heavy-duty spatulas are sturdy enough that you can easily smash the meat into the heat. They also come with a beveled edge which helps to scrape under the meat, releasing it from the cook surface. If you don't have a heavy-duty spatula, two normal spatulas can work. Take the two spatulas and make a large X with them. As you hover over the burger, start by using the bottom spatula to press the meat into the cooking surface, and then use the top spatula to press the bottom spatula to help it smash more simply.
