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
- Emulsify and thicken the dressing as they cook, giving it a rich body.
- Corn starch
- Thickens the mixture so it sets smoothly without becoming grainy.
- Melted butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Cream
- Adds fat and moisture, softening the texture and mellowing the tang.
- Vinegar
- Adds acidity for a sharp, tangy flavor that balances the richness.
- Sugar
- Adds sweetness that rounds out the acidity of the vinegar.
The step that matters
Gradually add the hot vinegar while stirring continuously. Adding hot liquid too fast can scramble the egg yolks, leaving lumps instead of a smooth dressing. Constant stirring spreads the heat evenly so the yolks thicken gently and the emulsion stays uniform.
Swap the mustard
