Cámara Agraria de la Comunidad de Madrid

I just got back front the monthly farmers’ market at the Cámara Agraria, which was excellent! It’s held on the first Saturday of each month in Casa de Campo, 10am — 3pm, within walking distance of the Lago subway station. There’s some information here:
It’s a medium size market, with all sorts of artisan cheese, meat, beer, oils, wines, pastries, breads and fresh produce. You’re buying direct from the producers, and pretty much every stall is offering (free) tasters. If you buy a glass for 1 Euro, you can even try the wine! The prices are very reasonable — I came back with piles of good eggs and yoghurt for substantially less than El Corte Inglés. I do recommend going early, as it gets pretty busy and things start running low around 1pm. Strongly recommend!
