Pour in the flour and mix first with a whisk, then knead the dough with your hands.
Form a ball from the dough and let it rise for an hour. Cover the dough with a towel.
Once the dough has risen, form small balls from it.
Pour more oil into a pot or large frying pan and wait a little until it heats up well over high heat. Then add the doughnuts and reduce the heat to medium.
Once they are browned on one side, flip them over to the other side.
The doughnuts are ready. If you wish, you can sprinkle powdered sugar on top.
