Process the potato through a cheese grater. Keep submerged in a bowl of water.
Drain the potatoes from the water and pat dry on a kitchen towel.
Tip off the water from the bowl, leaving the layer of potato starch at the bottom.
Toss the grated potatoes, panko, dill, egg, salt, and pepper together with the potato starch.
Heat olive oil in a pan.
Fry the latkes over medium heat for 3 minutes per side, shaping each piece with an egg ring.
Turn the heat on high, and give them another minute per side to crisp.
