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

What each ingredient does

Egg yolks
Emulsify with the butter and thicken the sauce as they gently cook.
Butter
Adds richness and body, and helps form a smooth emulsion with the yolks.
Tarragon vinegar
Provides acidity and sharp flavor, reduced to concentrate it into the base.
Shallots
Add aromatic sweetness and depth to the reduction.

The step that matters

Thickening over low heat. Egg yolks set at a narrow temperature range. Heating them too fast or too hot scrambles them, while gentle low heat and steady stirring let the yolks thicken the butter into a smooth emulsion.

Flavor stand-ins for the mace

How well each one fits the dish's main ingredients (shallot, clove, garlic, allspice, tarragon, vinegar, egg):

  1. Thymebetter flavor fit
  2. Capersbetter flavor fit
  3. Parsleybetter flavor fit
  4. Macethe original

Fit is the average pairing score against shallot, clove, garlic, allspice, tarragon, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
