Toast the cumin, coriander, and caraway seeds on a dry pan over low-medium heat. Toast only until they are fragrant.
Remove the seeds from the heat and, using a mortar and pestle, grind them into a powder.
Transfer the powdered seeds into a bowl, then add remaining ingredients. Mix thoroughly.
Serve immediately or store in an air tight container.
Notes
Like with harissa paste, choose your chili pepper wisely to add nuance to the harissa spice mix. Here are four excellent alternatives:- Ancho chilies: Mild and slightly smoky - Guajillo chilies: Mild and sweet - Chipotle chilies: Medium and smoky - Thai chilies: Hot and earthyLeave the seeds and any pith in when dicing for a hotter harissa. Remove the seeds for a milder version.
