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
- Hard boiled eggs
- Provide the whites that hold the filling and the yolks that form its base.
- Anchovies
- Add a salty, savoury depth to the yolk filling.
- Butter
- Adds richness and moisture, making the yolk mixture smoother and softer.
- Dry mustard
- Adds a sharp, pungent bite that balances the richness of the yolks.
The step that matters
Pound the yolks until smooth. Yolks must be broken down finely before anything is added, otherwise the filling stays lumpy and does not blend evenly with the butter and seasonings.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, pepper):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Mustardthe original
Fit is the average pairing score against egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
