The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: acetic acid (sour, vinegar).

Egg and nutmeg barely smell alike, yet cooks put them together in 24,744 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Egg yolks
Set into a firm custard when gently steamed, giving the soup its tender garnish.
Butter
Greases the shallow dish so the set custard releases cleanly.

The step that matters

Steaming the custard until firm. Egg proteins set gently at moderate heat. Too much heat or steam makes the custard porous or rubbery, so it should be steamed gently in warm water until just firm.

Swap the nutmeg

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

  1. Nutmegthe original
  2. Parsleyfits about as well
  3. Capersfits about as well
  4. Tarragonfits less well

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