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 ↓
Cooked Salad Dressing
Ingredients
Directions
Mix the oil and dry ingredients in a bowl.
Add the eggs and beat for five minutes.
Add the vinegar and beat for one minute.
Stir in the milk, then place the bowl in a pan of boiling water.
Cook until the sauce thickens to the consistency of thin cream, about ten minutes, stirring constantly.
If using butter, add it just before removing the sauce from heat.
Cool and bottle any unused sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate when heated, thickening the dressing into a smooth sauce.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavour.
- Milk
- Dilutes the mixture and adds richness and softness to the sauce.
- Mustard
- Adds sharp flavour and helps emulsify the fat into the sauce.
- Oil or butter
- Adds fat for richness and smooth mouthfeel.
The step that matters
Cooking the sauce over boiling water. Egg proteins set gently as the sauce heats. If the heat is too high or the sauce is not stirred constantly, the eggs can scramble and curdle, so the sauce should be cooked slowly and stirred until it thickens.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, milk, pepper, butter):
