A latke is a small pancake usually made with grated potatoes. Latkes are traditionally eaten during Hanukkah.
Most latkes are crispy little potato pancakes that are served with apple sauce or sour cream during the eight days of Hanukkah. Officially, though, a latke is simply a pancake—the word itself comes, via Yiddish, from a Russian word meaning "little pancake." Latkes can in fact be made from almost any vegetable, bean, cheese, or grain.
