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 ↓

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
- Mixed mustard
- Its natural emulsifiers help hold the oil and liquid together in a smooth dressing.
- Salad oil
- Provides fat that gives the dressing body and a silky mouthfeel.
- Milk
- Adds liquid and creaminess, diluting the oil into a lighter, pourable dressing.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness of the oil.
- Powdered sugar
- Adds a little sweetness to balance the acidity and sharpness of the vinegar and mustard.
The step that matters
Adding the oil drop by drop. Oil added too fast does not disperse into the mustard and liquid, so the emulsion can break and the dressing turns greasy and separated. Adding it slowly while mixing lets tiny oil droplets stay suspended.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, milk, vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Potatofits less well
- Cucumberfits less well
Fit is the average pairing score against sugar, milk, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
