What You Need to Know
Dry roasting the spices at 120–140 °C for 2–3 minutes initiates Maillard reactions and volatilizes aromatic terpenes, while preserving capsaicin and piperine. The resulting blend contains a balanced profile of spicy, earthy, and slightly sweet notes, with heat intensity modulated by the chili-to-other-spice ratio.
