After grating the potatoes, place them in a clean kitchen towel or cheesecloth. Squeeze out as much liquid as possible.
Transfer the grated potatoes to a large mixing bowl.
Add the finely chopped onion, eggs, flour, salt, black pepper, and baking powder to the grated potatoes. Mix well until combined.
Heat a generous amount of vegetable oil in a large skillet over medium-high heat.
For each pancake, drop spoonfuls of the potato mixture into the hot oil. Flatten each spoonful slightly with the back of the spoon to form a thin pancake.
Fry for 3-4 minutes on each side, or until golden brown and crispy.
Transfer the cooked pancakes to a plate lined with paper towels to drain any excess oil.
Enjoy your meal!
