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
- Melts with the flour to form the base of the white sauce, adding richness.
- Flour
- Thickens the melted butter and hot milk into a smooth white sauce.
- Hot milk
- Forms the liquid of the white sauce, which thickens as it heats with the flour.
- Hard-boiled eggs
- Provide the chopped whites that add body and the rubbed yolks that add a soft, rich topping.
The step that matters
Gradually whisking in the hot milk. Adding the liquid slowly while whisking keeps the flour dispersed, so the sauce thickens smooth instead of forming lumps.
Swap the parsley
How well each one fits the dish's main ingredients (egg, milk, butter, flour, pepper):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Cardamomfits about as well
Fit is the average pairing score against egg, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
