I.e. my chef friend had ground jalapeno at her apartment, shit was good. Like cayenne level heat but with a different flavor
I had to go to like an international food market to find some near me which is weird given how ubiquitous jalapeno peppers are
Sichuan is just kinda good in a bunch of stuff. I keep some Sichuan peppercorns in a pepper grinder, I think they need to be fried a bit to be activated but otherwise they add a fun flavor/spice to a lot of things
