Why it works: Milk and butter 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Its proteins set when heated, thickening the dressing and giving it body.
- Milk
- Provides the liquid base and creamy texture of the dressing.
- Butter
- Adds fat for richness and a smooth mouthfeel.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavour.
The step that matters
Cook until thickened. Egg proteins set gradually as the mixture heats. Cooking gently in a double boiler and stopping once it thickens keeps the dressing smooth, because overheating can scramble the egg and make it curdle.
Swap the mustard
How well each one fits the dish's main ingredients (milk, vinegar, butter, egg):
- Potatofits better
- Capsicumfits better
- Asparagusfits about as well
- Mustardthe original
Fit is the average pairing score against milk, vinegar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
