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
- Egg yolks
- Thicken the dressing as they set, giving it a creamy, emulsified body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the yolks and oil.
- Butter
- Adds fat that softens the texture and rounds out the flavour of the cooked base.
- Olive oil
- Adds fat and body, giving the finished dressing smoothness and a richer mouthfeel.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
The step that matters
Bring the mixture to a boil, then strain it. Egg yolks thicken as they heat, but overheating can curdle them into lumps. Straining removes any bits that set, leaving a smooth dressing.
