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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the main body of the puree and give it its green flavour and thick texture.
- Potatoes
- Add starch that helps the puree thicken and feel smooth and creamy.
- Cream or milk
- Adds fat and moisture, making the puree richer and silkier.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
The step that matters
Pass the mixture through a colander. Straining breaks down and removes fibrous skins and bits, so the puree comes out smooth rather than grainy or stringy.
Swap the white pepper
How well each one fits the dish's main ingredients (peas, potato, cream, butter, parsley):
- Tarragonfits better
- Thymefits better
- Celeryfits better
- White pepperthe original
Fit is the average pairing score against peas, potato, cream, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
