Roast the chilies. Remove the stems and place the dried chilies in a dry pan over low heat (no oil). Stir constantly for 3–5 minutes until slightly darkened and fragrant.
Cool completely. Transfer to a plate and let the chilies cool fully before grinding.
Grind. Grind using a mortar and pestle or pulse in a food processor until you get coarse flakes or a finer powder, depending on your preference.
