Latke

A latke is a type of potato pancake or fritter in Ashkenazi Jewish cuisine that is traditionally prepared to celebrate Hanukkah. Latkes can be made with ingredients other than potatoes such as cheese, onion, carrot, and zucchini. 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'.
