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 ↓

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
- Kidney
- Forms the main body of the dish and provides its meaty texture.
- Flour
- Thickens the gravy when heated with the butter and liquid.
- Butter
- Adds richness and fat, carrying flavour through the gravy.
- Cream or milk
- Supplies liquid and creaminess that becomes the gravy.
The step that matters
Boiling the gravy until it thickens. Flour only thickens fully when the mixture reaches a boil and the starch swells. Stopping early leaves a thin, floury sauce.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, flour, butter, egg, cream):
- Nutmegfits better
- Parsleythe original
- Tarragonfits about as well
- Capersfits about as well
Fit is the average pairing score against pepper, flour, butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
