Why it works: Pepper and parsley 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
- Egg yolks
- Thicken the mixture as they set and bind it into a smooth, spreadable custard.
- Lean ham
- Provides the savory meat base that gives the spread its main flavor.
- Butter
- Adds richness and a smooth mouthfeel to the mixture.
- Cream
- Adds moisture and softness, loosening the egg mixture for a creamy texture.
The step that matters
Cooking the mixture over low heat while stirring. Egg yolks thicken when gently heated, but high heat or no stirring can scramble them into lumps. Low heat with constant stirring keeps the mixture smooth and evenly thickened.
Swap the parsley
How well each one fits the dish's main ingredients (ham, egg, butter, cream, pepper):
- Nutmegfits about as well
- Parsleythe original
- Tarragonfits about as well
- Celeryfits less well
Fit is the average pairing score against ham, egg, butter, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
