If you use the same chillis I've used I'd guess it's getting pretty close to Mexican. But you gotta understand I'm in NZ so don't have the best grasp of how hot proper Mexican hot is. But please also understand that I often use superhots in cooking so there's that to consider too lol. This isn't quite as hot as the candied habaneros I also made today, but I'm guessing if the habs would make you perspire then these noodles might just make you slightly red faced?
