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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil-free dressing and gives it a thick, creamy body.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness of the cream.
- Cream
- Adds fat and moisture, giving the dressing a smooth, rich texture.
- Mustard
- Adds sharp flavour and helps bind the yolk and liquids together.
The step that matters
Mix just before serving. Cream and egg yolk dressings thin, separate or lose body if they sit, and the acid in the vinegar keeps working on the yolk. Holding the mix until serving keeps it smooth and fresh.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, vinegar, cream):
- Capsicumfits better
- Spinachfits about as well
- Mustardthe original
- Horseradishfits about as well
Fit is the average pairing score against egg, pepper, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
