As of today, the sauce is available at all U.S. locations of McDonalds (mcd). After first being introduced in 1998 to promote the film Mulan, the sauce gained a cult following, stoked by the television series Rick and Morty, which made an episode featuring the sauce. Fans of the show took to the streets in October when a limited release of the sauce quickly ran out.
Famous acolytes include musician Deadmau5, who reportedly bought a 64-gallon jug of the sauce on eBay for $15,000. He later shared it with fans at a concert.
The sauce will only be available while supplies last, so hurry down to your closest restaurant now—or, maybe, stay well clear.
