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
- Thickens the dressing as it cooks, giving it a creamy body.
- Milk
- Adds moisture and softness, diluting the egg so it thickens gently.
- Butter
- Adds fat for a smooth, rich mouthfeel.
- Vinegar
- Adds acidity for a sharp tang that balances the richness.
The step that matters
Cook until the mixture thickens. Egg proteins set gradually as they warm. Cooking gently in a double boiler keeps the heat low, so the egg thickens smoothly instead of curdling into lumps.
Swap the mustard
How well each one fits the dish's main ingredients (egg, milk, vinegar, butter):
- Potatofits better

- Asparagusfits about as well
- Mustardthe original
Fit is the average pairing score against egg, milk, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
