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

What each ingredient does

Eggs
Set into a soft, custard-like texture as they cook in the paper case.
Butter
Adds fat and richness, and keeps the egg from sticking to the paper.
Seasoned bread crumbs
Add a light crust and some browning on the surface of the egg.

The step that matters

Glaze the tops with a hot spoon. Egg whites set with heat, so the top stays runny until it is nearly done. A hot spoon finishes the surface gently, without overcooking the yolk underneath, which would turn it dry and rubbery.

Swap the parsley

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

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

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