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

What each ingredient does

Calf's feet
Collagen releases gelatin during long simmering, giving the broth body and a silky texture.
Egg yolk
Its proteins thicken gently when heated, giving the mixture a rich, creamy set.
Butter
Adds fat that softens the flavor and gives a smooth, rounded mouthfeel.
Sugar
Provides sweetness that balances the savory broth and the wine.
Sweet wine
Adds sweetness and fruity acidity that brighten the broth.
Lemon zest
Its aromatic oils add a fresh citrus fragrance to the finished broth.

The step that matters

Do not let the egg mixture boil. Egg yolk proteins set when hot, so if the mixture boils after the yolk is added it can curdle and turn grainy. Whisking in hot liquid slowly first keeps the yolk from scrambling.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Tarragonfits about as well
  3. Nutmegthe original
  4. Parsleyfits about as well

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