1Grate the Agria potatoes on a coarse grater, ensuring no water touches them.
2Place the grated potatoes onto a cloth, wrap it around to form a ball, and twist to squeeze out all the water.
3Place the squeezed potatoes into a bowl.
4Add a ladle and a half of clarified butter to a pan and place it on a low heat.
5Finely slice a white onion and break it up.
6Season the potatoes with fine salt and mix them well.
7Season the sliced onions as well.
8Build a solid base of potatoes in the pan, pushing them right into the corners and leaving a slight well in the centre.
9Add a thin layer of the seasoned onions into the well in the centre of the potato base, spreading them out nicely to the edges.
10Cover the onions with more potato on top.
11Leave the potato to set for a couple of minutes to allow the steam from underneath to cook the potatoes slightly.
12Once the potato is getting a bit softer, use a fish slice to tuck in all the potato trimmings around the side, shaping it into a perfect circle.
13Continue doing this motion of tucking in the potato trimmings until the color protrudes up the sides of the pan, indicating it's almost ready to flip.
14Once you get caramelisation coming up the side, hold the handle and rotate the potato in the pan to maintain a beautiful circular shape.
15After about 12 to 15 minutes, when the color is beautiful and golden up the sides, give it a final tuck in with the fish slice.
16Lift the rösti up with the fish slice and turn it over in the pan.
17Do the same process on the second side, checking for a beautiful golden crust and ensuring it's rolling around in the pan, indicating a crispy bottom.
18Lift it up, check the underside, and transfer it onto a rack to dry.
19Slice and serve the potato rösti.

Tips
Do not let water touch the potatoes to achieve a better crunch.
Potatoes always need a little more salt than you think.
Maintain the circular potato shape by rotating the pan as the potato crisps up.
