Choritos al vapor is a traditional mussel dish originating from the coastal areas of Chile. Although there are many variations, the dish is usually made with a combination of fresh mussels, garlic, white wine, onions, oregano, olive oil, and sometimes even longaniza sausage.
The onions, garlic, oregano and olive oil are sauteed in a large pan, then mixed with the mussels and white wine. The combination is cooked until the mussels open, and the dish is then served either directly from the pot or individually in large bowls.
