Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
To Dbess Salt Cod
Ingredients
Directions
Prepare the cod
Soak the salt cod in cold water until the salt is removed.
Bring the water to a boil, then remove from heat and let the fish sit in the water until tender.
Make the sauce
In a saucepan, melt the butter, then whisk in the flour and a few spoonfuls of water, seasoning with salt and pepper.
Heat the mixture until just boiling, then remove from heat and stir until smooth.
Add chopped parsley and thick cream if available.
Finish and serve
Remove the bones from the fish and combine it with the sauce before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 flesh, which must be desalted before cooking.
- Butter
- Enriches the sauce and carries flavour through its fat.
- Flour
- Thickens the butter and water into a smooth sauce.
- Thick cream
- Adds richness and body to the sauce when used.
The step that matters
Heat the sauce only until just boiling. Flour thickens as its starch swells with heat, but overheating or boiling hard can leave the sauce lumpy or thin. Removing it from heat and stirring keeps it smooth.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, pepper, cream):
- Nutmegfits better
- Parsleythe original
- Tarragonfits about as well
- Turmericfits about as well
Fit is the average pairing score against butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
