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

What each ingredient does

Tarragon vinegar
Provides the sharp, aromatic tarragon flavour that defines the sauce, concentrated by reduction.
Good butter sauce
Supplies the rich, buttery body and most of the volume of the finished sauce.

The step that matters

Reducing the tarragon vinegar. Reducing concentrates the vinegar's acidity and tarragon aroma. Reducing too far can make the sauce overly sharp, while too little leaves it weak in flavour, so the reduction should be watched closely.

Swap the tarragon

How well each one fits the dish's main ingredients (vinegar, butter, sauce):

  1. Tarragonthe original
  2. Capersfits about as well
  3. Garlicfits less well
  4. Parsleyfits less well

Fit is the average pairing score against vinegar, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
