Season the scored duck breasts with salt and pepper. Heat the corn oil in a non-stick frying pan until hot and add the duck breasts skin-side down. Cook for 5-8 minutes then turn and cook for a further 5 minutes on the other side, or until cooked to your liking. Remove from the pan and leave to rest.
Drain the excess fat from the pan and return to the heat. Add the vinegar, a splash of olive oil and the honey and scrape the sticky residue from the bottom of the pan into the liquid to make a sauce.
Add the juice from half the orange, the orange segments and the orange and lime zests. Finish the sauce by whisking in half the butter.
