They are firing up the horno at the Espanola Valley Farmers Market on Railroad Avenue. Dexter Trujillo (right) from Abiquiu leads a crew of young interns at the Market, showing them how to bake pizza, fruit pies and other culinary delights in a traditional horno that he helped build at the market. An horno is a beehive-shaped outdoor oven constructed of adobe bricks and plastered with mud that was used by the Native American pueblos and early Hispanic settlers to bake bread. Trujillo constructed a horno at the Smithsonian Institute in Washington, DC. The Farmers Market is held every Monday from 10 am until 4 pm.
