How to make
Wash and clean the potatoes and onions cut them into small cubes.
Fry them with the chopped onions and oil in a pre-heated pan, first at high heat and then lower it until they begin to redden slightly, then drain them well.
Add the fried potatoes and onions to the well beaten eggs and mix carefully. Pour the finished mixture into a suitable pan with 1-2 tablespoons preheated oil, stirring from time to time so that the raw mix on the top can seep down into the hardened mixture below it and also cook.
The moment the tortilla is cooked on the bottom, flip it over using a large plate or lid and fry that side as well. The point when you decide to flip it over depends on your personal preferences.
Some like it juicier, while others like it crispier.
