Once upon a time, I (a white Arizonan by background) served as a substitute cook at a homeless shelter hosted by a Lutheran church .
I made certain dishes as spicy as I normally ate them. But many of our guests and volunteers—including one Hispanic—complained that I made them MUCH too spicy!!!!
There’s no accounting for taste!
I’ve adopted this rule when cooking for others with peppers:
Divide by 8 (whatever heat is in the ingredients) and serve with several options for table seasoning/spike (salt, black pepper, cayenne and my Red Savina grinder).
Exception, of course, to those with like tolerance for heat.
