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 cook and set, giving it a creamy, spreadable body.
- Ham
- Provides the savory, meaty flavor that forms the main body of the topping.
- Cream
- Adds moisture and richness, keeping the mixture smooth rather than dry.
- Butter
- Adds fat for a rich flavor and smooth texture in the mixture.
The step that matters
Cook over low heat, stirring until the mixture thickens. Egg yolks set at gentle heat; high heat or no stirring can scramble them into lumps. Low heat and constant stirring give a smooth, thick custard-like topping.
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.
