Wash the chicken, separate the pieces and discard the fat but let the skin on. This will keep the chicken from drying out. Season with salt and pepper and put on a baking dish.
In a bowl combine orange juice, soy sauce, Hoisin, honey, mustard and grated ginger. Add to the chicken. Add the garlic.
You may prepare the chicken in advance up to this point. Cover and keep refrigerated, at least for two hours or overnight.
Preheat the oven to 350ºF.
Bake the chicken until golden brown, about 40 minutes. Transfer the chicken pieces to a plate, put the sauce in a small saucepan and bring to a boil.
Dissolve the potato starch in the water, and add slowly to the sauce, stirring until lightly thick.
Put the chicken pieces back in the baking pan, cover with the sauce, place half a peach on top of each piece, and continue baking for 10 minutes.
You may cook the peaches in a BBQ pan, if you want.
Serve the chicken with the peach on top, covered with the sauce. Put some white fluffy rice on the side, and serve with a lightly dressed green salad or carrot salad.
