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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Potatoes
- Form the bulk of the dish and soften as they cook, giving body to the stew.
- Milk
- Adds moisture and creaminess to the cooking liquid, forming a light sauce.
- Butter
- Adds richness and fat, carrying flavour through the sauce.
- All-purpose flour
- Thickens the milk mixture as it heats, giving the sauce body.
The step that matters
Bring to a boil after adding the butter and flour. Flour needs to be heated past a simmer to swell and thicken the liquid fully. Stirring while it heats prevents lumps from forming.
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.
