On May 5th, Taco Bell will be releasing a new hot sauce packet called “Diablo.”
The sauce is said to be hotter than Fire sauce (currently the hottest sauce Taco Bell has available) but also not as spicy as the Sriracha sauce they have on some tacos.
The sauce will be available for only a limited time (unless you really like it, which I can see them keeping it around).
If you aren’t into spicy foods, then this sauce probably isn’t right for you, but you also might not be impressed if you love spicy foods. I would consider it “pretty hot” but not “too hot.” Good luck quantifying that.
