Cheeseburger

A seared beef patty with American cheese laid on while it is still on the heat, so the slice melts into the crust and seals the meat. What the cheese changes runs through the whole sandwich.

Butter Burger

Wisconsin finishes its burger with butter meant to be tasted: Solly's has melted it over patties and stewed onions since 1936, Culver's toasts it into the bun, and state law still sides with the cow.
