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
- Made mustard
- Acts as an emulsifier that helps hold the oil and vinegar together.
- Salad oil
- Provides fat and a smooth, rich body to the dressing.
- Vinegar
- Adds acidity for sharpness that balances the richness of the oil.
- Sugar
- Adds sweetness that rounds out the sharpness of the vinegar.
- Milk
- Adds moisture and dilutes the vinegar, keeping the dressing smooth.
The step that matters
Add the salad oil drop by drop while stirring continuously. The oil must be broken into tiny droplets that the mustard can coat and hold in suspension. Pouring too fast lets the droplets merge and separate, so the dressing breaks instead of staying creamy.
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.
