Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the cod
Soak the salt cod in the refrigerator for 24 hours (or better yet, 48 hours) in several changes of cold water.
Drain the cod, rinse, and drain well again.
Remove bones and skin, and with your fingers pull the cod into small shreds; set aside.
Cook the onion, potatoes and cod
In a large heavy skillet set over very low heat, sauté the onion in 3 tablespoons of the olive oil about 15 minutes until very soft and golden, stirring now and then.
Meanwhile, stir‑fry the potatoes in the remaining oil in a second large heavy skillet over moderately low heat about 2 minutes until they begin to color; add the water, turn the heat to its lowest point, cover, and cook 15 minutes; set off the heat and reserve, still covered.
As soon as the onions are softly golden, mix in the cod and 1/2 cup of the milk, cover, and cook over lowest heat, stirring occasionally, 30 minutes.
Make the white sauce
While the cod cooks, prepare a white sauce: Melt the butter in a small heavy saucepan over moderate heat and blend in the flour; add the remaining milk and heat, stirring constantly, until thickened and smooth — about 3 minutes.
Blend in the white pepper and reserve.
Bake and serve
When the cod has only 10 minutes more to cook, preheat the oven to very hot (450).
When the cod is done, mix in the potatoes, white sauce, and cream.
Transfer to a buttered shallow 3‑quart earthenware casserole or au gratin pan.
Bake uncovered for 15 minutes, lower the oven temperature to moderate (350), and bake uncovered 25 minutes longer or until bubbly and tipped with brown. Serve at once.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt cod
- Provides the main flaky, savoury body of the dish once soaked and shredded.
- Potatoes
- Soften and thicken the mixture, giving it a creamy, starchy texture.
- Milk
- Forms the base of the white sauce, adding moisture and a smooth, creamy texture.
- Flour
- Thickens the butter and milk into a white sauce that binds the dish.
- Heavy cream
- Adds richness and fat, making the baked dish creamy and silky.
- Olive oil
- Cooks the onion gently and adds fat and flavour to the base.
The step that matters
Cooking the white sauce smooth. Flour must be cooked with the melted butter and whisked constantly as the milk is added; otherwise lumps form and the sauce does not thicken evenly.
Swap the white pepper
How well each one fits the dish's main ingredients (onion, olive, potato, milk, butter, flour, cream):
- Garlicfits better
- Capersfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against onion, olive, potato, milk, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
