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 sauce as they gently heat, and bind the liquid into a smooth body.
- Cream
- Adds richness and a smooth, silky texture.
- White wine vinegar
- Adds acidity that brightens the sauce and balances the richness.
- Mustard
- Helps stabilize the emulsion and adds a sharp, aromatic bite.
The step that matters
Stir continuously over low heat until scalded but not boiling. Egg yolks thicken when gently heated but scramble and curdle if the mixture gets too hot or is left unstirred. Constant stirring at low heat spreads the heat evenly and keeps the sauce smooth.
Swap the mustard
How well each one fits the dish's main ingredients (cream, egg, pepper, white wine, vinegar):
