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

What each ingredient does

French vinegar
Its acidity is concentrated by reduction, giving the sauce its sharp, piquant character.
Shallots
Provide a mild aromatic sweetness and savoury base as they soften in the reduction.
Espagnole sauce
Supplies the body and thickness of the sauce as the base for the finished dish.
Blond of veal
Adds rich savoury depth and body to the sauce.

The step that matters

Reducing the vinegar. Vinegar must reduce to about a third of its volume so its acidity concentrates and the flavour stays sharp rather than thin. Under-reducing leaves the sauce weak and watery once the Espagnole and veal are added.

Swap the thyme

How well each one fits the dish's main ingredients (shallot, capers, vinegar, pepper, sauce, veal):

  1. Tarragonfits better
  2. Parsleyfits better
  3. Thymethe original
  4. Marjoramfits about as well

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