Sopa albada and rastrojo soups Food and drink · Salinas de Pisuerga, Montaña Palentina, Palencia Image of Salinas de Pisuerga, not of the place itself. The Castilian soup has in Palencia two quite distinct versions: the sopas de rastrojo or toasted soups and the sopa albada, a gratinated garlic soup; both are made with round loaf bread and are served in the houses of the mountains.
