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
- Egg
- Thickens as it cooks gently and binds the dressing together.
- Butter
- Adds richness and a smooth, rounded mouthfeel.
- Cream
- Adds body and softens the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness.
- Sugar
- Adds sweetness that rounds out the sharp and sour notes.
- Mustard
- Adds sharp flavour and helps stabilise the emulsion.
The step that matters
Cook in a double boiler until it thickens slightly. The beaten egg thickens as its proteins set with gentle heat. Too much heat can scramble the egg and leave it lumpy, so use a double boiler and stop as soon as the mixture thickens.
