Why it works: Mustard and pepper 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 ↓

Egg and pepper barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their fat and richness give the filling a creamy, smooth texture.
- Mayonnaise
- Adds fat and moisture, helping the mashed yolks become smooth and spreadable.
- Mustard
- Adds sharp, acidic flavor that balances the richness of the yolks and mayonnaise.
The step that matters
Mash the yolks until smooth. Yolks mashed with mayonnaise and mustard need to be fully broken down so the filling is even and creamy. Lumps leave dry pockets and uneven texture in the finished filling.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper):
- Capsicumfits better
- Spinachfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
