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 ↓

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
- Butter
- Carries fat for richness and flavour, and cooks with the flour to form the base.
- Flour
- Starch thickens the liquid into a smooth, body-rich sauce as it heats.
- Milk
- Forms the liquid base that the starch thickens into a creamy sauce.
The step that matters
Gradually add the milk while stirring continuously. Adding liquid slowly while stirring keeps the flour dispersed, so the starch hydrates evenly and the sauce stays smooth instead of forming lumps.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, milk, pepper):
- Cinnamonfits better
- Nutmegfits about as well
- Cardamomfits about as well
- Parsleythe original
Fit is the average pairing score against butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
