Roasting a blend of pumpkin, sesame, coriander, and cumin seeds at controlled temperatures develops the deep, nutty flavor base of Guatemalan pepian paste.
Origin: Kaqchikel Maya (pre‑colonial) — highlands of Guatemala
See full technique reference →During roasting, Maillard reactions between reducing sugars and amino acids generate pyrazines and furans that impart a characteristic nutty‑roasted aroma. Simultaneously, controlled lipid oxidation produces volatile phenolics such as 4‑hydroxy‑2‑nonenal, while heat denatures lipoxygenase and peroxidase enzymes, reducing rancidity and extending shelf life.
