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

What each ingredient does

Oysters
Main ingredient, cooked gently until hot so they stay tender.
Egg yolks
Thicken the broth into a smooth, rich sauce when heated gently.
Cream
Adds richness and body, softening the broth's flavor.
Flour
Thickens the broth by absorbing liquid as it heats.
Butter
Carries the herb and ham flavors and adds richness to the broth.

The step that matters

Thicken with egg yolks. Egg yolks set when heated, so the mixture must stay below a simmer and be stirred constantly. Overheating can curdle the yolks and leave the sauce grainy.

Swap the onion

How well each one fits the dish's main ingredients (butter, ham, parsley, clove, flour, lemon, oyster):

  1. Shallotfits better

  4. Onionthe original

Fit is the average pairing score against butter, ham, parsley, clove, flour, lemon, oyster. Candidates are from the same food group and used in at least 100 recipes.
