Latke

A latke is a type of potato pancake or fritter in Ashkenazi Jewish cuisine that is traditionally prepared to celebrate Hanukkah. The word comes from the Yiddish latke, itself from the East Slavic oladka, a diminutive of oladya 'small fried pancake', which in turn is from Hellenistic Greek ἐλάδιον eládion, '(olive) oil', diminutive of Ancient Greek ἔλαιον élaion, 'oil'.
