Kalamazoo Special Burger Sauce

This is the hallmark sauce of our Smashburger and Patty Melt. Slather this slightly smoky, briny sauce on any burger or use it as a dip for grilled shrimp or crispy French fries. Burger sauce, or fry sauce, as it is also known, was popularized in Salem, Utah where it first appeared in 1955 at Stan's Drive-In.
