Why it works: Potato and parsley are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 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
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the cooking liquid into a light sauce that coats the potatoes.
- Milk
- Forms the creamy base of the sauce with the reserved potato cooking liquid.
The step that matters
Stir in the flour mixture before boiling. Flour must be whisked smoothly into cold milk first, then stirred into the hot liquid, so it dissolves without lumps and thickens evenly as it heats.
Swap the parsley
How well each one fits the dish's main ingredients (potato, milk, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Parsleythe original
- Thymefits about as well
Fit is the average pairing score against potato, milk, butter, flour. 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.
