Huesitos chocolate and bars Food and drink · Ateca, Comunidad de Calatayud, Zaragoza Image of Ateca, not of the place itself. José María Hueso founded here in 1862 an artisan chocolate factory; from it came in 1975 the wafer bar with hazelnut cream coated in chocolate called Huesitos. The plant still operates in the town and produces more than twenty million bars a year. Photo: Diego Delso (CC BY-SA 3.0) What to see and do in Ateca
