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
Beat the eggs in a bowl.
In a cup, mix sugar, mustard, and salt, then add to the eggs.
Stir in the milk and melted butter.
Heat the vinegar until boiling, then slowly stir it into the mixture.
If the dressing is not thick enough, place the bowl in hot water to cook.
Add a pinch of baking soda to the vinegar to prevent curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they cook and bind it into a smooth, creamy emulsion.
- Butter
- Adds richness and a smooth mouthfeel to the dressing.
- Milk
- Dilutes the mixture and adds softness and body to the dressing.
- Vinegar
- Provides sharp acidity that balances the sweetness and richness.
- Sugar
- Adds sweetness to balance the acidity of the vinegar.
- Baking soda (in the method)
- Neutralizes some of the vinegar's acidity to help prevent the egg mixture from curdling.
The step that matters
Adding the hot vinegar. Pouring hot vinegar in too quickly can scramble the egg proteins and cause curdling. Adding it slowly while stirring lets the eggs warm gradually so they thicken smoothly instead of setting in lumps.
Swap the mustard
