Place the potatoes on a clean cloth and gently squeeze
out as much moisture as possible. The more moisture you
remove, the crispier the finished rosti will be.
Heat 1/2 tablespoon of oil in a medium frying pan and
add a quarter of the potato to the pan.
Press down
on the potato with a metal spatula so that the bottom
turns crisp and golden brown. Flip the rosti and cook
the other side.
Season the cooked rosti with salt and pepper and serve
hot.
