Ingredients:
- 1 kg Russet potatoes, peeled
- 1 medium yellow onion
- 1 tsp lemon juice
- 2 large eggs, lightly beaten
- 0.25 cup all-purpose flour
- 1 tsp sea salt
- 0.5 tsp black pepper, freshly cracked
- 0.5 cup neutral oil for frying
- 1 tbsp Schmaltz (optional)
Instructions:
- Coarsely grate the potatoes and onion into a large bowl. Immediately transfer the mixture to the center of a clean kitchen towel. Twist and squeeze aggressively over a bowl until no more liquid drips out. Retain the liquid.
- Let the expressed potato liquid sit for 2 minutes until a white sediment forms at the bottom. Carefully pour off the top layer of brown water, leaving the thick, white potato starch at the bottom.
- Add the squeezed potato and onion mixture back into the bowl with the recovered starch. Add the beaten eggs, flour, salt, pepper, and lemon juice.
- Mix by hand until the flour is hydrated and the mixture feels tacky and holds its shape.
- Heat 1/4 inch of oil (and optional schmaltz) in a cast iron skillet over medium-high heat. Drop spoonfuls of the mixture into the hot oil, flattening slightly.
- Fry until the edges are deep mahogany and shattering-crisp, then flip and cook the other side. Transfer to a wire cooling rack to maintain texture.
