What You Need to Know
The dough is made from pre‑cooked masa harina, where nixtamalization removes hemicellulose and increases calcium, while partial gelatinization of starch improves plasticity. During cooking, starch gelatinizes between 55–65 °C and the Maillard reaction between lysine and reducing sugars begins around 140 °C, producing melanoidins that give the crust its color and complex flavor.
