Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Boiled Codfish and Oyster Sauce
Ingredients
Directions
Prepare the fish
Soak the fish in cold salted water for 30 minutes before cooking.
Roll the fish in a clean cloth dusted with flour and sew it up, ensuring one thickness of cloth.
Cook the fish
Place the fish in boiling water with a little salt, cloves, pepper, and lemon peel.
Cook until the fins pull out easily, then remove the fish.
Make the oyster sauce
For the sauce, scald the oysters in hot oyster liquor, then remove them.
Add salt, pepper, mace, and butter to the liquor, then whisk in milk mixed with flour.
Simmer briefly, add the oysters, and serve in a sauce-boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the dish, cooked gently in seasoned water until flaky.
- Oysters
- Add briny, savoury flavour to the sauce, and their liquor gives the sauce its base.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Milk
- Forms the creamy body of the sauce when combined with flour and heated.
- Flour
- Thickens the milk into a sauce and dusts the cloth so the fish does not stick to it.
The step that matters
Cooking the fish until the fins pull out. The fins loosening is the record's doneness cue. Overcooking dries and toughens the flesh, so the fish should be removed as soon as it is ready.
Swap the mace
How well each one fits the dish's main ingredients (flour, clove, lemon, oyster, fish, pepper, butter):
- Parsleyfits better
- Nutmegfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against flour, clove, lemon, oyster, fish, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
