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
- Eggs
- Thicken the dressing as their proteins set when heated.
- Cream
- Adds richness and body, softening the sharpness of the vinegar.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- Butter
- Adds fat for a smooth, rich texture.
- Mustard
- Adds sharp, pungent flavor that complements the vinegar.
The step that matters
Slowly add the boiling vinegar while stirring. Pouring the boiling vinegar in gradually while stirring warms the eggs slowly. Adding it quickly can scramble the eggs into lumps instead of letting the mixture thicken smoothly.
