Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oil
- Forms the body of the dressing and carries the flavours.
- Wine vinegar
- Adds acidity that gives the dressing its sharp, bright taste.
- Sugar
- Adds sweetness to balance the vinegar and salt.
- Dry mustard
- Adds pungent flavour and helps emulsify the oil and vinegar.
- Grated onion
- Adds aroma and savoury depth to the dressing.
The step that matters
Beat the oil, vinegar and water together first. Oil and water-based liquids separate on their own. Beating them thoroughly at the start breaks the oil into tiny droplets, so the dressing looks blended and stays more uniform before the other ingredients go in.
Swap the onion
How well each one fits the dish's main ingredients (wine, vinegar, sugar, mustard, pepper):
- Horseradishfits better
- Capsicumfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against wine, vinegar, sugar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
