Instructions
Place 1/4 of the potatoes, onion, eggs, salt, flour, and baking powder in the bowl of a food processor; pulse several times until the vegetables are finely chopped. Add remaining potatoes and pulse again until all potatoes are finely chopped and mixture is thoroughly combined.
Heat canola oil in a skillet over medium heat. Scoop up about 1/3 cup of potato mixture at a time and place in skillet. Fry latkes until brown and crisp on the bottom, 2 to 3 minutes. Flip and cook other sides until brown, 2 to 3 minutes longer.
Repeat with remaining potato mixture, replenishing oil as needed. Serve hot.
