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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the dish and soften into a tender base as they boil.
- Milk
- Cooks the potatoes and forms the liquid that becomes the sauce.
- Flour
- Thickens the milk so the mixture turns creamy rather than watery.
- Butter
- Adds richness and a smooth, silky mouthfeel to the finished sauce.
The step that matters
Thicken with flour mixed in cold milk. Flour added directly to hot liquid clumps, because starch grains swell unevenly on contact. Whisking it into cold milk first disperses the starch so it thickens smoothly once heated.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, milk, flour, butter, pepper):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits about as well
- Thymefits about as well
Fit is the average pairing score against potato, milk, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
