Thicken and flavour
In a saucepan, combine tarragon and cider vinegars and bring to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard flour
- Provides the main mustard flavour and forms the thick body of the sauce.
- Tarragon vinegar
- Adds acidity and a sharp, aromatic flavour that balances the mustard.
- Cider vinegar
- Adds acidity that sharpens the flavour and helps preserve the mustard.
- White wine
- Adds mild acidity and depth of flavour during simmering.
- Celery seeds
- Contribute a savoury, aromatic flavour to the mustard.
The step that matters
Pour the hot vinegar mixture into the mustard cream and stir until thickened. Mustard flour thickens as it combines with the hot liquid, but stirring unevenly can leave lumps. Adding the hot vinegar gradually while stirring keeps the cream smooth and evenly thickened.
Swap the clove
How well each one fits the dish's main ingredients (mustard, flour, tarragon, vinegar, cider, white wine, celery):
- Fennelfits better
- Thymefits better
- Capersfits better
- Clovethe original
Fit is the average pairing score against mustard, flour, tarragon, vinegar, cider, white wine, celery. Candidates are from the same food group and used in at least 100 recipes.
