In the latest sign that America's favorite southeast Asian condiment has gone totally mainstream, McDonald's is now testing a Sriracha Big Mac in 126 restaurants in the Columbus, Ohio area. The burger chain is also offering a Sriracha Mac dipping sauce there, which it had tested earlier this year in custom burgers in San Diego, Seattle, and Los Angeles. McDonald's, which recently has been tinkering with its iconic menu items to keep customers interested, announced that the Big Mac would be also available in a mini and a grand size for a few weeks in early 2017.

A spokesperson said the use of Sriracha sauce now marks the first time the chain has switched out the ingredients in the sandwich for a new flavor profile. "This is a milestone for McDonald's," she wrote in an email to BuzzFeed News. Tweet 1
