The cheese is made from cow's milk from cows milked in the afternoon or evening and heated between 25 °C and 30 °C (77-86 °F) with a coagulant added so the milk forms curds.
The resulting cheese is normally white (blanco), with a red (rojo) variety is also made where Spanish smoked paprika (pimentón) in its "sweet" and/or "spicy" ("picante") varieties are added to the cheese before moulding to shape using the form ("Troncado"-Trunk) or cloth bag ("Trapo" or "Trapu").
