Weigh potato, egg, yellow onion, all-purpose flour, neutral oil, apple, sour cream, kosher salt. Latkes is cooked in Hanukkah as its own plate, not as a copy of a restaurant menu. Fry shredded potato and onion into crisp cakes and serve them with apple and sour cream. They are the Hanukkah pancake. Amounts are for 4 from foods this library can count.
