The variety of cereal used is usually yellow maize, but often buckwheat, white maize, or mixtures thereof may be used. Coarse grinds make a firm, coarse polenta; finer grinds make a creamy, soft polenta. Polenta is a staple of Northern Italian, Swiss and Balkan (where it is also called kačamak) cuisines (and, to a lesser extent, the Central Italian one, e.g. Tuscany) and its consumption was traditionally associated with lower classes, as in times past cornmeal mush was an essential food in their everyday nutrition. In Romania and Moldova, this dish is known as mămăligă. It is also a staple dish in Argentina.
