In this recipe video, rich-tasting caramelized onions combined with Madeira wine make a spectacular sauce for chicken livers. Serve the delicious pan sauce with rice or over toast to soak up all the juices, and you won't miss a single drop. If you don't have any Madeira on hand, substitute the more commonly available sherry. Top this amazing dish with egg and parsley for a rustic, country-style feast!
