Peel and wash potatoes. Cut into slices about 1 cm thick and then into sticks.
Place potatoes in a bowl with cold water so that they do not get black.
Heat the oil (which should be enough to cover the potatoes).
Drain in a strainer and add a little salt.
Put in potatoes gradually so that they are covered by the oil. Don’t stir before 5 minutes have passed and then stir occasionally until the desired colour.
If you use a deep fryer the same as above applies but then follow the instructions of your fryer as to how long to fry.
Serve hot sprinkling some oregano and extra salt on top.
