The first Smashburger was created in Ashland, Kentucky. The original Dairy Cheer hamburger shop owner, Bill Culvertson, created the Smashburger when his employee discovered that smashing the meat with a No. 10 bean can while grilling was a great way to get the best flavor into a burger. With this specific cooking technique, there will be a Maillard reaction where the juices caramelize and give the meat a crunchy side while enhancing its flavor.
