- 1 large baking potato (about 10 oz) peeled and quartered lengthwise
- 1/2 onion, peeled and quartered
- 1/4 flour
- 1 egg
- Coarse salt and pepper
- 1/2 teaspoon baking powder
- High-heat oil for frying
Using a food processor fitted with a coarse grating disk, or using a hand grater, grate the potato and onion; discard any large pieces. Transfer the mixture to a clean dish towel and squeeze out any excess liquid, then transfer to a large bowl. Stir in the flour, egg, 3/4 tsp. salt, 1/4 tsp. pepper and the baking powder.
In a medium skillet, heat 1/4 inch oil over medium-high heat until hot but not smoking. Working in 5 to 6 batches, drop 2-tbsp. scoops of batter into the pan about 2 inches apart. Using a spatula, flatten the batter into disks. Cook, turning once, until browned and crisp, about 5 minutes. (Lower the heat if the latkes darken too quickly.) Drain on paper towels.
