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
- Yolks thicken the dressing as they cook, and whites add lightness when folded in.
- Butter
- Adds richness and a smooth, velvety body to the dressing.
- Vinegar
- Adds acidity that balances the richness of the yolks and butter.
- Sugar
- Adds sweetness that rounds out the sharpness of the vinegar and mustard.
- Mustard
- Adds sharp flavour and helps emulsify the dressing.
The step that matters
Cooking the yolk base over simmering water. Egg yolks thicken as their proteins set with gentle heat. If the heat is too high or stirring stops, the yolks can scramble and turn grainy, so stir constantly and keep the water simmering, not boiling.
