McDonald's to bring back its Szechuan sauce beginning March 31

McDonald's is bringing back its fan-favorite condiment Szechuan sauce starting March 31 exclusively through its app for a limited time.

Fans will be able to select it to accompany their Chicken McNuggets or purchase up to five containers a la carte.

The Szechuan sauce has a savory and slightly sweet taste with hints of soy, garlic, ginger, and mild vinegar.

McDonald's first released the sauce in June 1998, when Disney's Mulan premiered in theaters and the fast-food giant briefly offered the Szechuan sauce in its Chicken McNuggets happy meal to accompany the film. The happy meal came with a set of Mulan toys.

It returned twice more before it announced on Sunday that it is “dropping Szechuan Sauce nationwide exclusively on the McDonald's Apps next week!”

The Szechuan sauce gained fans after it was referenced in the first episode of the third season of Adult Swim's Rick and Morty in April 2017. It featured Rick going to McDonald's to taste the sauce in a dream sequence.

Viewers Rick and Morty then began petitioning McDonald's on social media to bring back the sauce.
