Bacalhau com natas

Portugal's national dish, 'cod with cream'. The trick lies in the combination of béchamel sauce and cream, which envelops the salty, fibrous fish in a silky, gratinated duvet. Here, the potato is not a side dish but provides the structure of the meal.

Instructions

1

Boil the soaked cod in hot water for 10 minutes, then drain (reserve a little of the liquid). Remove skin and bones, and flake the meat.

Tip: The fish fibres separate under heat, making it easy to debone.
2

Dice the potatoes and fry them in plenty of oil (or parboil) until semi-soft, but do not fry until completely crisp as they will soften further in the oven.

Tip: Pre-frying seals the potato surface so it doesn't soak up all the sauce, maintaining its texture.
3

Sauté the onions and garlic in olive oil, add the fish, and fry together for a few minutes.

Tip: The sweetness of the onion counterbalances the saltiness of the fish.
4

Prepare the béchamel: melt the butter, stir in the flour (white roux), then gradually pour in the milk and cream. Cook until thickened.

Tip: The starch granules in the flour open up in the hot fat and thicken the sauce by absorbing liquid (gelatinisation).
5

Combine the fish mixture, potatoes, and sauce. Pour into a baking tray, sprinkle with cheese, and bake at 180°C for 25 minutes until the top is golden brown.

Tip: Gratinating (browning with cheese) gives the dish its final, complex flavour.

Recipe FAQ

It turned out too salty, what should I do?
Salted cod (bacalhau) must be soaked thoroughly (at least 24 hours, changing water multiple times). If it's still salty, increasing the amount of potatoes and cream can tone it down.
