Roasted Duck with Orange

Clean the duck and marinate it in oregano for approximately 8 hours

Cook the duck in a greased roasting pan, topped with slices of prosciutto, and put it in the oven

When the duck starts to release its juices, remove one cup of sauce and mix it with half of the orange juice concentrate

Keep basting the duck with this mixture until it's very tender

When the duck is done, remove all the sauce

Cook the remaining orange juice concentrate with the flour dissolved in milk, stirring constantly until thickened

Serve the sauce separately and garnish with slices of orange, serving the duck alongside.
