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
Dredge a clean cloth with flour and wrap the fish, sewing the edges to fully enclose it.
Place the wrapped fish in boiling water with a little salt, cloves, pepper, and lemon peel.
When the fins pull out easily, the fish is done.
Remove the fish and arrange it on a napkin.
Make the oyster sauce
Scald the oysters in hot oyster liquor, then remove them.
Add salt, pepper, mace, and butter to the liquor.
Whip in the milk with flour.
Simmer briefly, add the oysters, and serve in a sauceboat.

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 boiling water until flaky.
- Flour
- Thickens the milk sauce and helps the cloth wrapping hold the fish together.
- Oysters
- Provide the briny, savoury flavour that defines the sauce.
- Oyster liquor
- Carries the oyster flavour into the sauce as its cooking liquid.
- Milk
- Adds creaminess and body to the sauce.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
The step that matters
Whipping the milk into the flour. Adding flour and milk without whisking smoothly can leave lumps, because flour clumps when it meets liquid. Whisking the flour into the milk first and then adding it to the hot liquor gives an even, smooth sauce.
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.
