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
- Thicken the dressing as they set during gentle cooking, giving it a creamy body.
- Vinegar
- Adds acidity that gives the dressing its tang and balances the sweetness.
- Milk
- Adds moisture and richness, softening the dressing's texture.
- Mustard
- Adds sharp flavor and helps emulsify the oil into the dressing.
- Oil
- Adds fat for smoothness and a rounded mouthfeel.
The step that matters
Stirring over the double boiler. Eggs set when heated, so constant stirring and gentle heat in the double boiler keep the mixture smooth instead of scrambling it into curds.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, vinegar, milk):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
