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

What each ingredient does

Calf's feet
Release gelatin into the water, which sets the cooled liquid into a jelly.
Jelly
Provides the gelatin base that gives the finished broth body and a silky texture.
Egg yolk
Adds richness and helps thicken the broth as it gently warms.
Butter
Adds fat for a smoother mouthfeel and rich flavor.

The step that matters

Stir quickly but do not let it boil. Egg yolk thickens by gentle heat and will scramble or curdle if the mixture boils, leaving a grainy broth instead of a smooth one.

Swap the nutmeg

How well each one fits the dish's main ingredients (sugar, wine, butter, egg):

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Tarragonfits less well
  4. Thymefits less well

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