What You Need to Know
These techniques rely on heat transfer from heated stones to food, raising temperatures to 90–120 °C for earth ovens and 250–300 °C for roasting. The resulting gelatinization of potato starches and denaturation of meat proteins release sugars and amino acids that react via Maillard pathways, producing melanoidins and caramelized flavors.
