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 ↓

Flour and butter 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
- Cold boiled potatoes
- Form the bulk of the dish and give it a soft, tender texture.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Drawn butter
- Adds fat for richness and a smooth mouthfeel.
- Hot water
- Adds moisture that loosens the flour and butter into a sauce.
The step that matters
Simmer and stir often. Flour can clump and scorch on the bottom of the pan if left unstirred. Frequent stirring keeps the starch dispersed so it thickens the sauce evenly.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter, parsley):
- Shallotfits better
- Chivefits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against flour, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
