Subway, the fast food place micromanagers probably love, is testing a creamy sriracha sauce at select locations. The spicy sauce was spotted by the folks over at Foodbeast.

Currently, Subway’s spiciest sauce is probably their Chipotle Southwest Sauce, which I don’t think is at all spicy. Last summer, the sandwich chain tested a wasabi sauce, but it has yet to show up nationwide.

Brand Eating posted a review of the new sauce:

The sauce is a bright, almost neon orange; it almost makes you think you should take a Geiger counter to it. I figured I might as well just taste it by itself and dabbed some on my finger. I got some sweet tanginess paired with creaminess before the heat hit me. Wow! This is some seriously spicy stuff!

I hope this rolls out nationwide. But if not, I guess I could take the bottle of sriracha in my fridge and splooge some of it on my next Subway sandwich.
