Just when you thought American’s love affair with that hot-sauce-of-the-moment Sriracha was beginning to wane, the largest fast food chain in the country has begun experimenting with the spicy red sauce: select McDonald’s restaurants in San Diego are reportedly offering a Sriracha-Big Mac Sauce hybrid. 

Discover San Diego reports that some locations within the city are serving as testing ground for the special sauce as part of a signature crafted menu intended to provide customers with more options.

The new option is reportedly made with white cheddar, kale, spinach, crispy onions, tomato and a secret blend of Sriracha and traditional Big Mac sauce.

The San Diego Golden Arches are also offering a slew of other sauce options including pico guacamole and maple bacon dijon.

It really shouldn’t come as a huge surprise that McDonald’s would jump on the increasingly crowded Sriracha bandwagon. Customers have long suggested the fast food joint provide them with Sriracha for their meals, but mostly as a garnish.

Of course, McDonald’s isn’t the only company taking advantage of the spicy sauces’ popularity. Last year, Heinz spiced things up with a new Sriracha-flavored ketchup, and Pizza Hut offered a Honey Sriracha Dynamite pizza featuring a Honey Sriracha sauce with a Honey Sriracha crust edge and honey Sriracha sauce drizzle.

Before that, McDonald’s rival Taco Bell reportedly tested Sriracha-flavored menu items, while Pringles also waded into to the Sriracha market with a limited-time offering at Walmart.
