Musannaf Ibn Abi Shayba 28:149

Abu Usama narrated to us, from Hisham, from al-Hasan, who said: He used to dislike eating from what the Magians cooked in their pots. And he did not see any harm in eating from their food other than that, such as ghee, bread, *kamikh* (a type of condiment), *sirar* (a type of cheese or preserved food), or milk.
