Peel (or don't) the potatoes and cut them into sticks. They should be roughly 1 x 1 cm in thickness.

Place the potato sticks in a bowl with lukewarm water.

Drain the water and refill the bowl with lukewarm water.

Repeat the process once more. Now you will see that the water has become clear, which means most of the starch has been removed from the potatoes.

Bring a pot of water, vinegar, and salt to a boil and add the potato sticks to it.

Let it boil for 7 minutes.

Drain the water from the potatoes and place them on a clean kitchen towel.

They need to dry and cool down. I usually give them 20-30 minutes in the freezer, so they become cold and dry.

Put the potatoes in a bag and add 2 tbsp of oil. Close the bag and shake well to distribute the oil.

Place them in your airfryer/actifry and cook them for 25-30 minutes at 200 degrees Celsius (392 degrees Fahrenheit).

They should change color and then they are ready.

Pour them out onto a clean kitchen towel and season with salt on top.

Serve immediately.
