A tapas bar favorite is tortilla Española – or Spanish omelette as it’s known around the world. However, it’s not just a tapas treat. Tortilla can also be eaten as a main dish, a break time snack, or even in a sandwich, which is popular with kids. To create your own tortilla, you’ll need to slowly fry up onions and potatoes in olive oil before adding the egg. This will caramelize the onions and give your omelette that extra sweetness. If you’re feeling adventurous, though, why not try adding chorizo and spinach? But be warned, as delicious as this new combination is, the locals won’t let you call it a tortilla!
