Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mustard flour
Forms the bulk of the paste and provides the mustard's pungent flavor and thick body.
Cider vinegar
Adds acidity that sharpens the flavor and balances the heat of the mustard.
Tarragon vinegar
Contributes acidity and a distinct herbal aroma to the mustard.
White wine
Adds acidity and a mellow fruity note as the mixture simmers.

The step that matters

Pour the hot vinegar mixture into the mustard cream and stir until thickened. Mustard's pungent compounds develop when the flour is moistened and then hydrated, and heat and acid set the thickened texture. Adding the vinegar too early or without stirring can cause lumps or flatten the heat, so the paste thickens unevenly.

Swap the clove

How well each one fits the dish's main ingredients (mustard, flour, tarragon, vinegar, cider, white wine, celery):
