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
i'm only familiar with it from yunnan, lao, viet and thai food, but yeah after reading up on it it seems it's more common in central/south american/carribean food than in mexican food
