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 ↓

Directions
Make the dressing
Bring the vinegar and butter to a boil.
In a bowl, beat together the sugar and egg yolks.
Add the mustard (mixed with a little cold water) and salt to the egg mixture.
Stir this mixture into the boiling vinegar, stirring constantly until it thickens without boiling.

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 gently in the hot vinegar, giving body and richness.
- Vinegar
- Provides the sharp acidity that defines the dressing and helps keep it stable.
- Butter
- Adds fat for a smoother, rounder mouthfeel in the dressing.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Mustard
- Adds sharp flavour and helps emulsify the dressing.
The step that matters
Stirring the egg mixture into the boiling vinegar. Egg yolks thicken through gentle heat; if the mixture boils or is added too fast, the yolks can scramble. Stir constantly and remove from heat once it thickens without boiling.
