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
- Potatoes
- Break down into a smooth, thick body that gives the soup its substance.
- Floured butter
- Its flour thickens the liquid and the butter adds richness and mouthfeel.
- Beaten eggs
- Coagulate with gentle heat, adding body and a silky richness to the soup.
- Milk
- Adds creaminess and softness, mellowing the flavour of the potato base.
The step that matters
Add the milk and egg mixture to the hot soup. Eggs set when heated, so they can curdle or scramble if the soup boils hard after they go in. Stir over gentle heat only as long as the record says, keeping the mixture smooth.
Swap the parsley
How well each one fits the dish's main ingredients (potato, butter, milk, egg):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Dillfits less well
Fit is the average pairing score against potato, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
