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
- Eggs
- Thicken the dressing and add richness as they set gently with heat.
- Cornstarch
- Thickens the liquid when heated, giving the dressing body.
- Butter or oil
- Adds fat for smooth mouthfeel and carries flavour.
- Milk
- Adds moisture and mildness, loosening the thick custard-like base.
- Vinegar
- Adds sharp acidity that balances the richness of the eggs and fat.
- Mustard
- Adds savoury flavour and helps keep the fat blended into the dressing.
The step that matters
Cooking over hot water until it thickens. Egg proteins set at moderate heat, so overheating can scramble the eggs into lumps. Gentle, steady heat lets the starch and eggs thicken the dressing smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, milk, vinegar):

Fit is the average pairing score against egg, butter, milk, vinegar. Candidates are from the same food group and used in at least 100 recipes.
