The US craze over Szechuan sauce - which Chinese netizens from the actual Sichuan province have said tastes nothing like local Sichuan sauce - can be likened to Singapore's fervour for McDonald's curry sauce.
It led to a petition on Change.org asking for the sauce to be brought back.
McDonald's responded. It was only to be available for a very limited time on Saturday, and only in select stores.
Some "Rick and Morty" fans waited in line for hours to get the limited sauce but still left empty handed when the sauce ran out.
McDonalds offered the throwback dipping sauce and an accompanying poster Saturday as part of a one-day promotional event for the animated TV series, "Rick and Morty".
Wubba lubba grub-grub, it looks like the world is still gripped by Szechuan sauce fever thanks to a one-off joke by Adult Swim's Rick and Morty.
Yesterday, we were truly humbled by the wonderful curiosity, passion, and energy this community showed to welcome back Szechuan Sauce - even just for one day. An episode earlier this year featured Rick and Morty, a sociopathic scientist and his grandson, in an adventure trying to obtain the rare McDonald's Szechuan dipping sauce.
However, the promotion quickly backfired when fans - some of whom had reportedly queued for hours - were told the sauce had ran out.
While it was troubling to hear reports that some McDonald's employees were trying to sell the sauce under the table, that wasn't almost as upsetting as the fact that some bad apples felt this was a big enough problem to start fights, with some locations having police involved in the fallout that followed. That caused a lot of backlash on social media. Lots more #SzechuanSauce and locations.
"Our super-limited batch, though well-intentioned, clearly wasn't near enough to meet that demand", the company said in a release.
If you're not among the few who scored some of McDonald's rare Szechuan Sauce, you may be in luck.
