Why it works: Parsley and pepper 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 ↓

Flour and butter 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
- Codfish
- Forms the main body of the dish and provides its savory flavor.
- Rich milk
- Makes the liquid base of the cream, adding moisture and richness.
- Flour
- Thickens the milk into a smooth cream as it heats.
- Butter
- Adds fat and richness, and helps the flour blend smoothly.
- Egg
- Adds body and richness to the cream once it is cooked.
The step that matters
Add the flour-butter mixture to the hot mixture. Flour clumps if it goes into liquid unevenly. Rubbing it smooth into the butter first helps it disperse, so the cream thickens evenly without lumps.
Swap the parsley
How well each one fits the dish's main ingredients (egg, milk, flour, pepper, butter):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Cardamomfits about as well
Fit is the average pairing score against egg, milk, flour, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
