Divide and peel the chicken legs. Salt and pepper. Fry in the oil or clarified butter on all sides in a large non-stick pan. Now put the onion cut into half rings in the pan, after 2 minutes add the apple cubes (peeled). Let some paint draw in. Add the chicken pieces and the quartered oranges, then add the orange juice. Simmer for about 20 minutes with the lid on. Now stir in the brandy and the chopped mint. Let simmer for another 10 to 15 minutes.
Take out the meat. Squeeze the oranges with a wooden spoon, do not serve. Season the sauce with salt and pepper and, if necessary, thicken with ice-cold butter.
Rice, potato croquettes or baguettes are enough as a side dish.
