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
In a bowl, mix the dry ingredients with the egg yolks and beat until light.
Add the melted fat, cold milk, and hot vinegar.
Cook in a double boiler until the mixture coats the spoon.
If the mixture curdles, place the boiler in a pan of cold water and beat until smooth.
You can use one whole egg instead of two yolks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they set and bind it into a smooth emulsion.
- Flour
- Stabilises the mixture so it thickens without curdling during cooking.
- Butter
- Adds richness and a smooth mouthfeel to the dressing.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavour.
- Milk
- Dilutes the egg and flour mixture, adding moisture and softness.
The step that matters
Cook in a double boiler until the mixture coats the spoon. Egg yolks set at moderate heat and curdle if overheated. Gentle indirect heat thickens the dressing evenly, and the coats-the-spoon test shows when it is ready.
