Remove the fat and skins from the chicken breasts, wash them, fry them in a little clarified butter or oil until they are lightly browned on both sides (approx. 5 minutes). Remove from pan and set aside. Then sauté the onion and apple in the pan. Season with honey, mustard and vinegar and pour in some water. Add the salted and peppered chicken breasts again and simmer together over a low flame for about 30 minutes. Finally, peel off with a little creme fraiche and serve with rice. A nice mixed salad with it!
