Once by my land Zamora was named to the sellers of Jaras (Cistus landanifer) for the oven to cook the bread, especially in the area of Yago. Jara has also been used to cook pottery and ceramic objects as it still happens in moving, near the Arribes del Duero, where they craft the prettiest ceramics in Spain. They were also used in the shingles of this area, now missing. Dead the trade, Jariego has degenerate into lazy, lazy, perritraco, as they also say in Extremadura.
