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

What each ingredient does

Eggs
Provide the main body of the dish, with the whites forming the shell and the yolks forming the filling.
Melted butter
Adds richness and a smooth, moist texture to the mashed yolk filling.
Sweet cream
Adds moisture and softness to the mashed yolk filling, making it spreadable.
Oyster
Adds a briny, savory flavor inside each egg white cavity.

The step that matters

Keep the eggs warm but not cooking. Egg whites and yolks set with heat, so holding them just warm keeps the whites tender and the filling smooth. Too much heat turns the yolks chalky and rubbery.

Swap the parsley

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

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Capersfits less well
  4. Tarragonfits less well

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