Tortilla Española

Tortilla Espaola, or Spanish omelette as it's known around the world, is another tapas bar favorite. It's not just a tapas treat, though. Tortilla can be used as a main dish, a snack, or even a sandwich, which is popular among children.

To make your own tortilla, first fry onions and potatoes slowly in olive oil before adding the egg. This will caramelize the onions and add sweetness to your omelette. If you're feeling particularly daring, try adding chorizo and spinach. But, as tasty as this new combination is, the locals will not allow you to call it a tortilla!

It's just eggs, potatoes, and onions – and some purists believe that adding onion is a gastronomic sin of the highest order. The Spanish omelette is a whole lot more than its parts. To make a tasty meal out of almost nothing, add chorizo, ham, spinach, courgettes, or whatever else you have on hand.
