McDonald’s is bringing back a 19-year-old cult classic, Szechuan Sauce, for one day only in select markets across the country, including five locations in Central and Southern California.

The dipping packets, served only with the chain’s newly introduced buttermilk crispy tenders, is available Saturday, Oct. 7 at two Los Angeles area restaurants: 8507 Artesia Blvd., Bellflower and 1231 S. La Brea, Los Angeles. No locations are serving the savory and sweet sauce in Orange County or the Inland Empire.

Other locations serving the sauce in California: 2345 El Cajon Blvd. San Diego, 2699 Mount Vernon Ave. Bakersfield, and 1213 State Street, Santa Barbara.

The sauce, which contains soy, ginger, garlic and vinegar, was originally served in 1998 with chicken nuggets. McDonald’s is serving it as a bonus to promote its new tenders, which debuted last week.

Select restaurants are also giving away limited-edition posters designed by artists from Delicious Design League with purchase of the tenders. The Oct. 7 giveaways begin at 2 p.m. local time while supplies last. Select restaurants will also have limited quantities of stickers of the poster designs while supplies last.
