Season the duck on both sides with salt and pepper.
When the butter is foaming place the breasts in skin-side down.
Cook for 3 minutes or until the skin is nicely golden and crisp.

Transfer the duck to the oven and cook for a further 7 minutes or until cooked to your liking.
Remove from the oven and leaves to rest.
