Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pure mustard
- Provides the main body and sharp flavour that the spiced vinegar liquid is mixed into.
- White vinegar
- Supplies the acidity that gives the mustard its tang and helps it stay stable.
- Onion
- Adds savoury sweetness and aromatic flavour to the infused liquid.
The step that matters
Let the liquid cool slightly before mixing in the mustard. The mustard is added to the strained liquid, so it should be cooled rather than hot. Very hot liquid can dull the sharp volatile compounds in mustard, weakening its pungency, and the mixture thickens more predictably once it is no longer steaming.
Swap the clove
How well each one fits the dish's main ingredients (vinegar, tarragon, onion, garlic, mustard):
- Capersfits better
- Thymefits better
- Dillfits better
- Clovethe original
Fit is the average pairing score against vinegar, tarragon, onion, garlic, mustard. Candidates are from the same food group and used in at least 100 recipes.
