Meanwhile, boil slowly ¾ cup of wine, apple preserves and shallots, in a small heavy saucepan for about 6 minutes, until the glaze is slightly thickened. Add the chopped sage and chili powder. Brush half of the glaze on the chicken and cook for about 10 minutes. Then brush the remaining glaze and roast, until it is well cooked and the glaze is bubbling. Transfer it to the hot platter.
