Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the yolk filling and the white cups that hold it.
- Butter
- Adds fat and richness, making the yolk mixture smoother and creamier.
- Mustard
- Adds sharp flavour that balances the richness of the yolks.
- Vinegar
- Adds acidity that brightens the flavour of the rich yolk mixture.
The step that matters
Mix the yolks with butter, salt, and mustard until fine.. Yolks must be broken down completely to a smooth paste; lumps leave a grainy texture. Fat from the butter helps the mixture blend evenly and feel creamy on the palate.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, vinegar):
