What You Need to Know
The dough ferments at 30–35 °C for 1–2 h, developing gluten and leavening. During frying at 175–190 °C, the Maillard reaction (140–165 °C) and sugar caramelization generate brown pigments and aromatic compounds, while the gluten network traps steam to keep the interior moist. Precise thermal control prevents oil absorption or charring, ensuring the characteristic texture and flavor.
