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
Green chili flakes are cool. They’re milder than red chili flakes, so you can get more of the pepper flavor for the same amount of heat.
Freeze dried shallots are also fire. A little expensive, but it’s a good lazy source of allium flavor.
