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 yolks
- Thicken the dressing as they cook and give it a rich, custard-like body.
- Cornstarch
- Stabilizes the cooked mixture so it thickens smoothly without curdling.
- Egg whites
- Add airy lightness when folded in just before serving.
- Butter
- Adds richness and a smooth, silky mouthfeel.
- Vinegar
- Adds acidity that gives the dressing its tangy bite.
- Sugar
- Balances the acidity with sweetness.
The step that matters
Cook in a double boiler, stirring constantly. Egg yolks can scramble if they get too hot or cook unevenly. Gentle indirect heat and constant stirring let the mixture thicken smoothly as the starch and yolk proteins set.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, butter, vinegar, cream, pepper):
