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
Cardamom is a nice one which is common in Indian cuisine but underutilized elsewhere
I use freshly ground cardamom in my home made waffles. It’s awesome
