Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dry mustard
- Provides the main body and sharp pungent flavour once hydrated by the liquid.
- Vinegar
- Adds acidity and sharpness, and turns the dry powder into a spreadable paste.
- Olive oil
- Adds fat, giving the mustard a smoother, more rounded mouthfeel.
- White sugar
- Adds a little sweetness that balances the sharpness of the vinegar and mustard.
The step that matters
Adding the vinegar gradually while beating. Dry mustard must be hydrated slowly to form an even paste. Adding too much liquid at once leaves dry lumps, while beating helps the particles absorb the liquid and release their pungent compounds evenly.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, pepper, olive, vinegar):
- Capsicumfits better
- Mustardthe original
- Tomatofits about as well
- Cucumberfits less well
Fit is the average pairing score against sugar, pepper, olive, vinegar. Candidates are from the same food group and used in at least 100 recipes.
