Peel the potato and grate it with a Korean grater, mid-size grater, or blender/food processor.
Strain the grated potatoes for a couple of minutes.
Set aside the strained water and wait for a couple of minutes until the water and the starch from the potato has separated. Carefully throw away the water while leaving starch.
Combine the potato and potato starch, season with salt and pepper, and mix thoroughly.
Heat your nonstick pan with two tablespoons of oil.
When pan is heated, lay all the potatoes flat and even (You have 15 seconds to do this).
Let the potatoes cook and brown on one side while making sure it doesn’t stick to the pan. After a couple of minutes flip the potatoes.
While cooking the other side of the potatoes, add more oil or spread a knob of butter around the edges to help the potatoes crisp up.
Flip as needed until crispy on both sides.
Serve and enjoy!
