How do the Xi'an feel about spicy food?

So one idea, well, maybe I won't get in trouble for this. Something that we're leaking out is that they taste food a little bit differently than we do. So one of their big things is different texture of food more than flavor. This is because they tend to eat more fermented and rotting foods by nature. So their sense of taste isn't quite the same as ours. So they like foods that tingle or numb or feel prickly and stuff like that.
