Instructions
Divide the ground beef into six equal portions, rolling them into balls about the size of a golf ball to a mandarin orange. Gently compress to remove excess air, then chill them uncovered in the fridge.
Whisk together all the sauce ingredients in a small bowl until smooth. Chill until ready to use.
Preheat the griddle to medium-high. Lightly oil the surface and toast the buns, top side down, until golden and crisp. Set aside.
Crank the griddle to high and add a little more oil. Place the chilled beef balls on the hot surface, then use a heavy burger press or sturdy spatula to smash each one firmly into a thin patty.
Season with salt and let them sizzle for 2 to 3 minutes, until the edges are browned and crispy. Flip, top with cheese, and cook for another 1 to 2 minutes until melted.
Spread the special sauce generously on the toasted buns. Add the patties and your favorite toppings — lettuce, tomato, pickles, or grilled onions. Serve immediately.
Notes
Don't press down after the initial smash — let them develop that crust undisturbed.
