Cheeseburger

What is it?

Small and built on a regular bun, this fast-food burger uses a thin beef patty cooked on a flat-top grill, a slice of American cheese, diced onions, pickles, ketchup, and mustard. The cheese goes on while the patty's still hot, so it softens instead of fully melting. Compared with McDonald's Quarter Pounder line, the patty here is smaller and thinner, and the overall build leans more on bun and condiments than meat. It's assembled to order from a short list of ingredients, with the familiar sweet, sharp, and salty notes stacked in a very compact package.
