Actually, we attempted to copy Smashburger with these. Pretty darn close. Ground beef, 15% fat, rolled into balls of about 1/4 pound each. Melt a bit of butter on a griddle warmed to 400 degrees. When butter sizzles, add meat and smash it down thin with a spatula. Let burgers cook until there's a brown crust. Flip and cook for just a couple more minutes. They'll be done quickly after the flip. Butter soft buns and place butter-side-down on the griddle until browned. Add your favorite burger goodies. For us, it was a little bacon, mayo-ketchup mixed, tomato, lettuce and onion. Butter is magical.
