Ajiaco should not be frozen below -18 °C, because especially the chicken meat is sensitive to temperature and bacteria could develop. After freezing, the ajiaco can be kept for about 2 months. The ajiaco should be completely cooled before you freeze the soup. Make sure you freeze small portions. You should never refreeze a defrosted portion. Of course, your ajiaco will lose flavor if you freeze it. It is always recommended to prepare the soup fresh.
