Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Cooked Salad Dressing
Ingredients
Directions
Make the dressing
In a bowl, mix sugar, salt, dry mustard, and egg yolks.
Add oil, milk, and vinegar to the mixture.
Transfer to a saucepan and heat until thickened.
Finish and serve
Beat egg whites until stiff and gently fold into the thickened mixture.
Remove from heat immediately to prevent curdling.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
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 with gentle heat and add richness.
- Egg whites
- Add lightness and airy texture when beaten and folded in.
- Oil
- Adds fat for a smooth, rich mouthfeel.
- Vinegar
- Provides acidity that gives the dressing its tang.
- Sugar
- Balances the acidity with sweetness.
The step that matters
Remove from heat immediately. Egg yolks coagulate when overheated, so the mixture can curdle or turn grainy. Pulling it off the heat as soon as it thickens keeps the dressing smooth.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, milk, vinegar):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Sweet potatofits about as well
Fit is the average pairing score against sugar, egg, milk, vinegar. Candidates are from the same food group and used in at least 100 recipes.
