McDonald’s will be serving its Big Mac sauce — also known as secret sauce and special sauce — in condiment dipping cups for a limited time.
You have to order through the McDonald’s app to get the cups, according to a news release from the fast food giant.
The promotion will begin April 27 at participating U.S. locations and run as long as supplies last. The chain followed a similar strategy last year when it brought back its Szechuan Sauce, a favorite thanks to a “Rick and Morty” cartoon.
The sauce will be delivered in a blue and silver cup, the colors of Big Mac wrapping when the burger was introduced in 1968.
