Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
In a saucepan, combine egg yolks, dry mustard, sugar, vinegar, and butter.
Heat over a double boiler on low heat, stirring constantly until thickened.

Add salt to taste after the dressing is done if milk is used.

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 set with gentle heat, giving it a creamy body.
- Vinegar
- Adds the sharp acidity that gives the dressing its tang.
- Butter
- Adds richness and a smooth mouthfeel to the dressing.
- Sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
- Dry mustard
- Adds a sharp, pungent flavor that complements the eggs and vinegar.
The step that matters
Stirring over low heat until thickened. Egg yolks set at moderate temperatures, so heating too fast or letting the mixture boil can curdle or scramble them. A double boiler and constant stirring keep the heat gentle and even.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, vinegar, butter, pepper, milk):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
