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 ↓
Stewed Salt Cod
Ingredients
Directions
Prepare the cod
Scald the soaked cod by boiling it in water for 10 minutes.
Scrape the cod to remove skin and bones, then flake it.
Make the stew
In a stew-pan, combine the flaked cod with butter and flour.
Add enough milk to moisten the mixture and stir well.
Let it stew gently for 10 minutes.
Season with pepper to taste and serve hot.
Serve
Transfer to a deep dish, top with sliced hard-boiled eggs, and garnish with parsley.

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
- Soaked cod
- Forms the main body of the dish; scalding and flaking make it tender and easy to break into pieces.
- Butter
- Adds richness and a smooth, rounded flavour to the stew.
- Flour
- Thickens the milk and cod mixture into a soft, cohesive sauce.
- Milk
- Moistens the flaked fish and forms the creamy liquid of the stew.
The step that matters
Stewing gently after adding the milk. Flour thickens liquid only when it is heated enough to swell its starch. Stirring well while adding milk prevents lumps, and gentle heat keeps the sauce smooth rather than scorched or broken.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, egg):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Cardamomfits about as well
Fit is the average pairing score against butter, flour, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
