Locos por la tortilla (Crazy about Spanish omelet)

Cooking tips to cook the most traditional spanish dish

- It is not necessary to slice the potatoes paper thin, and it is best not to use a food processor because most will slice the potatoes too thin, and they stick together.

- How do you know when oil is hot enough to fry the potatoes and onions? Drop a single piece of potato or a bit of bread into the oil. It should sizzle.

- Remember to watch the heat while frying. If the oil is too hot, the potatoes will brown rapidly on the outside, but will be raw on the inside.

- After frying potatoes, place the potato and onion mixture in a colander for a few minutes to allow more oil to drain. If you do this, place a plate underneath to catch the olive oil and you can use it again.
