This is a basic recipe for one of Portugal's most famous comfort foods. Feel free to add your own twists once you've mastered it, or keep it classic!
If you can't find potato sticks, you can make your own by chopping potatoes into thin matchsticks and frying them until crispy. You can also add extra ingredients; Maura likes to add shredded carrot and leeks to the onion and garlic mixture, and chopped prawns along with the cod.
