Ostiones a la veracruzana is a traditional appetizer originating from Veracruz and the Gulf region. The dish is made with a combination of oysters, butter, oil, onions, garlic, tomatoes, jalapeños, flour, white wine, parsley, and seasonings.

The onions and garlic are sautéed in oil, then mixed with the jalapeños, tomatoes, oysters, and water in order to create a thin sauce. Another saucepan is used to heat the flour in oil until golden, and it's then mixed with white wine so that the flour dissolves.

The oysters with the sauce are mixed with the roux, and the combination is boiled and seasoned with salt and pepper. The dish is garnished with chopped parsley just before serving.
