For this recipe, I use either muscovy duck, a brazilian breed which is known for its incredible flavor and lean profile, or wild-hunted duck. Other breeds, such as moulard or pekin, will do fine, but be aware that the principal difference among these types of duck is the fat cap underneath the skin. With any breed of duck, to cook it properly, you want to render the fat from under the skin of the breast at a cooking temperature and time that will allow the skin to brown perfectly, once all the excess fat is rendered away. For all breeds, lightly score the duck breast, skin side, so that the skin is pierced (freeing the fat to render away), without going into the flesh of the breast. To do this, you will need a sharp knife. Score the breast at 45 deg. angles, so you end up with a diamond pattern on the skin side of the breast.
