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 ↓
Boiled Dressing
Ingredients
Directions
Prepare the base
Mix the dry ingredients in a bowl.
Moisten the mixture with vinegar and stir in the beaten eggs.
Add the cream and mix well.
Add the butter
Clarify the butter by melting it, letting the salt settle, and pouring off the liquid.
Add the clarified butter to the dressing.
Cook and cool
Place the bowl in a pan of boiling water and stir constantly until it thickens like custard.
Remove from heat, strain, and cool before serving.

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 set with gentle heat, giving it a custard-like body.
- Cream
- Adds richness and moisture, softening the sharpness of the vinegar.
- Vinegar
- Provides acidity that gives the dressing its tang and balances the richness.
- Clarified butter
- Adds fat for smoothness and a rich mouthfeel.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
The step that matters
Cooking over boiling water while stirring constantly. Egg proteins set at moderate heat, so the dressing thickens smoothly. If it gets too hot or is left unstirred, the eggs can scramble and curdle.
