Bon Appétit joins burger scholar Chef George Motz, owner of Hamburger America, to see how the best smash burgers in NYC are made. Smash burgers got their name from the technique of smashing patties on a hot griddle to lock in flavor and create a crispy crust. Motz demonstrates how he makes The Chester, Oklahoma Fried Onion Burger, and his classic smash burger, which have made Hamburger America one of the most talked about burger spots in New York City.
