Grate the Potatoes and Onion:Peel and grate the potatoes using a box grater. Grate the onion as well.
Remove Excess Liquid:Place the grated potatoes and onion in a clean kitchen towel or cheesecloth and squeeze out as much liquid as possible. This step is essential for achieving crispy pancakes.
Mix the Batter:In a large mixing bowl, combine the drained potatoes and onion. Add the eggs, flour, salt, and pepper. Mix well until evenly combined.
Heat the Oil:Heat vegetable oil in a large skillet over medium heat. Add enough oil to coat the bottom of the pan generously.
Fry the Pancakes:Scoop about ¼ cup of the potato mixture for each pancake and drop it into the hot oil. Flatten with the back of a spoon to form a thin pancake.Fry for 3-4 minutes on each side, or until golden brown and crispy.
Drain and Serve:Remove the pancakes from the skillet and place them on a plate lined with paper towels to drain excess oil. Serve warm with your favorite toppings.
