Market Report: In Barcelona, Spain, olives and rovellon mushrooms are specialties of the season

On a trip to Catalonia, Spain in early November, I visited an array of markets -- from the bustling and touristy Mercat de la Boqueria in central Barcelona, to a smaller, neighborhood market in an off-the-beaten-track part of town, to a small sidewalk market in the Mediterranean beach resort of Sitges 25 miles south of the city. I found olives -- lots of different types of olives -- and some other regional specialties of the season, such as calcot onions and rovellon mushrooms.
