1. Pat the skate wings dry and lightly powder them with flour. Season the skate generously with salt and pepper.
2. In a sauté pan, heat the butter and oil on medium high heat. After the butter has melted and begins to foam, carefully add the skate and allow it to fry for 4 minutes on each side.
3. Carefully remove the skate from the pan and cover it with foil.
4. Leaving the excess butter sauce in the pan, add the lemon juice and capers. Keep on medium heat. Cook until the sauce turns golden brown, then remove from the stove and sprinkle in the parsley.
5. Remove the foil from the skate and carefully spoon on the sauce before serving.
