I wish it were causal. I eat a ton of Sriracha.
I've found it to be the best spicy I've ever eaten: it does not leave the mouth (no throat or lip burn, does not go up your nose), the crescendo is soft (if you dilute it), and takes no more than 20min to go away after your last bite.
But it is, I recall it once was the hottest sauce in Hot Ones[0].
I end up drinking about a liter of ice water and have to pause my eating several times. I often end up shivering after due to the sweating and the ice water.
Yum!
