The Whopper sandwich is the signature product sold by the international fast-food restaurant chain Burger King in the global market. Introduced in 1957, it has under gone several reformulations including resizing and bread changes. The sandwich is one of the best known products in the fast food industry; it is so well known that Burger King bills itself as the Home of the Whopper in its advertising and signage.
The company markets several variants of the sandwich to cater to different customer wants as well as other variants that are specifically tailored to meet local taste preferences or customs of the various regions and countries in which it does business. To promote continuing interest in the product, Burger King will occasionally release limited time variants on the Whopper, such as its Angry Whopper line, which change or add different ingredients.
The Original Whopper sandwich is a hamburger, consisting of a flame grilled quarter-pound (113.4 g) beef patty, sesame seed bun, mayonnaise, lettuce, tomato, pickles, ketchup, and sliced onion. Optional ingredients such as processed cheese, bacon, mustard or jalapeño peppers may be added upon request. Regional and international condiments include BBQ sauce, salsa and guacamole. Burger King will also add any condiment it sells, including tartar sauce, honey mustard, steak sauce and hot sauce.
Different promotional varieties have appeared throughout the years for a limited time.
