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 ↓

Ingredients
Directions
In a saucepan, heat the vinegar alone until warm.
In a bowl, whisk together the egg yolks, olive oil, mustard, flour, sugar, salt, and red pepper.
Slowly add the warm vinegar to the mixture while whisking continuously.
Return the mixture to the saucepan and bring to a boil, stirring constantly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and thicken the dressing as they set with heat.
- Olive oil
- Adds fat and richness, giving the dressing a smooth body.
- Flour
- Thickens the liquid so the dressing becomes spoonable rather than runny.
- Vinegar
- Provides the sharp acidity that defines the dressing's flavor.
- Sugar
- Balances the acidity of the vinegar with a touch of sweetness.
The step that matters
Return the mixture to the saucepan and bring to a boil, stirring constantly.. Egg yolks can scramble if overheated or left unstirred. Constant stirring keeps heat even, and the starch from the flour thickens the dressing as it cooks.
Swap the mustard
How well each one fits the dish's main ingredients (egg, olive, flour, sugar, vinegar, pepper):
- Capsicumfits better
