Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. 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
- Butter
- Enriches the sauce with fat, giving it a smooth, rich mouthfeel.
- Cream or rich milk
- Forms the liquid base of the sauce, adding richness and body.
- Flour
- Thickens the cream as it heats, giving the sauce body so it coats the potatoes.
- Cold boiled potatoes
- Form the bulk of the dish and absorb the creamy sauce.
The step that matters
Thicken with flour, stirring until it boils. Flour must be stirred in evenly and brought to a boil so its starch swells and thickens the cream. Lumps or an unboiled sauce will leave the dish pasty or floury-tasting.
Flavor stand-ins for the parsley
How well each one fits the dish's main ingredients (butter, pepper, cream, flour, potato):
- Nutmegabout as good a flavor fit
- Parsleythe original
- Celeryabout as good a flavor fit
Fit is the average pairing score against butter, pepper, cream, flour, potato. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
