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 ↓
Codfish Axd Macaroni
Ingredients
Directions
Prepare the fish
Soak the salt codfish overnight.
Steam the codfish until tender, then remove all bones and break it into small flakes.
Layer and make the sauce
Layer cooked macaroni on a dish, followed by a layer of fish and a few slices of hard boiled eggs.
Repeat with more macaroni and a final layer of fish on top.
In a saucepan, melt the butter, then stir in the flour, salt, and pepper until creamy.
Add the hot milk and stir until thickened.
Assemble and serve
Pour the sauce over the fish and macaroni, sprinkle with minced parsley, and serve hot.

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 codfish
- Provides the main savory flavor and flaky texture of the dish.
- Butter
- Enriches the sauce and carries flavor as the base for the roux.
- Flour
- Thickens the butter and milk into a smooth, creamy sauce.
- Hot milk
- Forms the liquid base of the sauce, which thickens as it heats with the flour.
- Cooked macaroni
- Provides the starchy body that holds the layers together.
- Hard boiled eggs
- Adds richness and a soft, creamy texture between the layers.
The step that matters
Stir the sauce as it thickens. Flour must be cooked briefly in melted butter and whisked into hot milk to avoid lumps. Stirring keeps the starch dispersed so the sauce thickens smoothly rather than clumping.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, flour, pepper, milk):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Cardamomfits about as well
Fit is the average pairing score against egg, butter, flour, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
