What You Need to Know
Roasting at 120–150 °C initiates Maillard reactions that reduce bitterness and develop flavor precursors. Subsequent grinding with water and gentle heating to 70–80 °C mobilizes theobromine, catechins, and polyphenols, while capsaicin from chili can modulate perceived heat. Controlled oxidation of catechins during heating improves mouthfeel and color.
