I say, and with God's help: Liquids such as butter, oil, and fat are purified by pouring water over them three times and then lifting it away. As for other liquids like honey and molasses, they are purified by pouring water over them three times until they return to their original state. See: Nihayat al-Mirad by Abdul Ghani al-Nabulsi, pages 331-343, and God knows best.
