A recipe for a traditional Spanish dish called Tortilla de patatas is provided. It calls for potatoes, sausages, eggs, onion, garlic, salt, and milk. The potatoes are chopped and fried, then mixed with fried onion, garlic and sausage. The potato-sausage mixture is combined with beaten eggs and milk before being cooked in a pan until set, forming the omelette-like main dish known as tortilla.
