Ever since it was randomly featured in an episode of Adult Swim's cult comedy, Rick and Morty, McDonald's Szechuan dipping sauce - which was discontinued 20 years ago - has become something of a legend among fans.
The fast food chain tried to appease condiment-hungry customers last year by bringing the fabled sauce back for a single day, but quantities were so sparse that the whole thing was deemed a disaster.
However, this year, McDonald's is making amends by shipping out 20 million packets of the stuff to every branch in the US. And, in an unprecedented move, the fast food giant is going on the record to explain how the release last year went so wrong.
The sauce, which was originally released in 1998 to promote Disney's Mulan, will be available in McDonald's all across the country, starting from 26 February. But with numbers limited, you'll have to act fast if you intend to get your hands on some.
And now McDonald's has also partnered with OnionLabs and Studio@Gizmodo for a podcast called The Sauce, which promises to lift the lid on what went wrong in October of last year.
Andrew Harding, head of Studio@Gizmodo and director of The Sauce, told The A.V. Club: "We were surprised how candid McDonald's was willing to be about what happened on October 7, and how ready they were to let us get to the bottom of all this."
"[The Sauce] became a look into all the angles. It's the inside story of how one of the world's biggest companies responds to what went wrong in the good-intentioned giveaway - from how it all started to how they contained it to how they're now trying to make it right.
"Whether you're a customer that never got to try it, or just a general podcast fan who's intrigued by the unique glimpse behind the curtain, we think you'll find The Sauce to be the most fascinating podcast about a condiment ever made."
Catherine LeClair, who hosts the three-part series, says she's always found pop culture crazes to be fascinating on a human level.
"Exploring the Szechuan sauce saga of October 7 2017 took that fascination to a new level," she added.
"I talked with fans who were so obsessed with a sauce they had never tasted that they drove across an international border to get it. And I also got to speak with corporate executives and Chef Mike at McDonald's, who hold themselves responsible for what went wrong.
"It's rare that a company as big as McDonald's will pull back the curtain and give you the honest story behind their missteps, and McDonald's was willing to do that."
