Why it works: Vinegar and mustard 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
- Coagulate when heated gently, giving the dressing its thick, creamy body.
- Vinegar
- Adds acidity that balances the richness and sharpens the flavour.
- Butter
- Adds fat for smoothness and a rounder, richer mouthfeel.
- Mustard
- Adds sharp flavour and helps emulsify the fat into the mixture.
- Sugar
- Adds sweetness to balance the vinegar's sharpness.
- Cream
- Loosens the thickened base and adds richness and a softer texture.
The step that matters
Steam until thick, stirring occasionally. Eggs thicken as their proteins set with gentle heat. Too much heat or no stirring can scramble them into lumps, so keep the heat gentle and stir often.
