Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Provide the rich, creamy base of the filling.
- Melted butter
- Adds fat and moisture, making the yolk filling smooth and silky.
- Mustard
- Adds sharpness that balances the richness of the yolks.
The step that matters
Mix the yolks until smooth. Mixing the yolks with melted butter while they are still warm and thoroughly blended gives an even, smooth filling. Lumps of yolk stay dry and crumbly, so the filling can look uneven and taste less creamy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, butter):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Mustardthe original
Fit is the average pairing score against egg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
