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 layer of cloth covers it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main body of the dish, cooked gently in boiling water until flaky.
- Oysters
- Add briny, savory flavor to the sauce and tender bite when scalded and returned to it.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Milk
- Forms the creamy base of the sauce, giving it body and mild sweetness.
- Flour
- Thickens the milk so the sauce turns smooth and coats the oysters.
The step that matters
Whisking the milk and flour into the liquor. Flour must be fully blended into the milk before it is added, and the sauce simmered briefly, so it thickens smoothly without lumps. Adding it too fast or unmixed can leave clumps of starch that never dissolve.
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.
