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 ↓
Deviled Eggs
Ingredients

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Form the creamy, rich base of the filling once mashed smooth.
- Butter
- Adds fat that makes the yolk filling softer and smoother in texture.
- Vinegar
- Adds a sharp acidity that brightens the rich yolk filling.
The step that matters
Mash the yolks until smooth. Lumps of yolk leave the filling grainy and hard to pipe or spoon neatly. Mashing the yolks well before adding the butter and vinegar gives an even, creamy texture that blends evenly with the other seasonings.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, pepper, vinegar):
- Tarragonfits about as well
- Parsleythe original
- Dillfits less well
- Thymefits less well
Fit is the average pairing score against egg, butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
