Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 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
- Form the starchy body of the dish, which softens and becomes fluffy when mashed.
- Cold milk
- Adds moisture and creaminess, loosening the mash into a smooth texture.
- Butter
- Adds fat for richness and a silky mouthfeel.
- Flour
- Helps thicken the mash slightly when mixed with the butter.
The step that matters
Stir in the butter rolled in flour until melted. Flour coated on the butter disperses evenly and thickens the mash without lumps. Stirring until fully melted keeps the texture smooth rather than greasy or pasty.
Swap the parsley
How well each one fits the dish's main ingredients (potato, milk, butter, flour, pepper):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits about as well
- Thymefits about as well
Fit is the average pairing score against potato, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
