Big Mac
The Big Mac is a McDonald’s hamburger made with two beef patties, a sesame-seed bun, cheese, lettuce, pickles, onions, and Big Mac sauce.
Hamburger: A sandwich consisting of a cooked ground-meat patty served in a split bun. The Big Mac is a layered variation on the hamburger.
Big Mac sauce: A creamy, tangy McDonald’s condiment formulated for the Big Mac. It supplies the sandwich’s signature flavor and distinguishes its dressing from ordinary ketchup.
Jim Delligatti: An American McDonald’s franchisee credited with creating the Big Mac. Delligatti developed the sandwich at his Pittsburgh-area restaurant.
Big Mac Index: A comparison of Big Mac prices across countries used as an informal measure of purchasing-power parity. The sandwich’s standardized global sale makes it a convenient currency-comparison benchmark.
Sesame seed: The edible seed of the sesame plant, used as a food ingredient and garnish. Sesame seeds cover the Big Mac’s top bun.
Club sandwich: A layered sandwich traditionally made with poultry, bacon, lettuce, tomato, and toasted bread. Its stacked construction offers a useful comparison to the Big Mac’s middle bun layer.
Pittsburgh: A city in western Pennsylvania, United States. The Big Mac was first sold in the Pittsburgh area in 1967.
Brand identity: The visible and verbal elements through which an organization presents its brand. McDonald’s uses the Big Mac’s name, packaging, and imagery as recognizable brand assets.
American cheese: A mild, processed cheese product that melts readily. A slice adds a soft, mild cheese layer to the sandwich.
Hamburger bun: A soft, round bread roll designed to hold a hamburger patty and toppings. The Big Mac uses a three-part bun, including a middle slice.
