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.
Remove from heat immediately to prevent curdling.
Finish with egg whites
Beat egg whites until stiff and gently fold into the mixture.

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 and add richness as they set with gentle heat.
- Egg whites
- Whipped to stiff peaks, they add lightness and volume to the dressing.
- Oil
- Adds fat and a smooth, rich mouthfeel to the dressing.
- Vinegar
- Provides acidity that gives the dressing its tangy flavor.
- Milk
- Adds moisture and mild richness, softening the sharpness of the vinegar.
The step that matters
Remove from heat immediately to prevent curdling. Egg yolks thicken as their proteins set with heat, but overheating causes them to scramble and curdle. Pulling the pan off the heat once the dressing thickens keeps it 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.
