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
- Thicken the dressing as they cook, giving it a custard-like body.
- Cream
- Adds richness and a smooth, fat-based mouthfeel to the dressing.
- Vinegar
- Provides the acidity that gives the dressing its sharp, tangy flavour.
- Mustard
- Adds sharp, pungent flavour that balances the richness of the cream and eggs.
The step that matters
Cook in a double boiler until it reaches the consistency of boiled custard. Egg proteins set gently as they heat. Direct heat can curdle the eggs, so gentle indirect heat in a double boiler and constant stirring keep the dressing smooth.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, egg, cream):
- Horseradishfits about as well
