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 ↓

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 set gently with heat.
- Melted butter
- Adds richness and a smooth, creamy mouthfeel to the dressing.
- Vinegar
- Provides acidity that brightens the flavor and balances the richness.
- Sweet milk
- Thins the mixture and adds mild dairy flavor and body.
The step that matters
Cook over low heat while stirring constantly. Egg yolks thicken through gentle heat but can scramble if they get too hot or are left unstirred. Low heat and constant stirring let the mixture thicken smoothly into a dressing.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, milk, vinegar, sugar):
- Capsicumfits about as well
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against egg, butter, milk, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
