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

What each ingredient does

Eggs
Set into a delicate structure as they cook, forming the body of the omelet.
Butter
Coats the pan to prevent sticking and adds richness to the flavor.
Milk
Adds moisture, keeping the cooked omelet tender rather than dry.

The step that matters

Cook until set, then fold. Cooking over medium heat sets the eggs gently without browning or toughening them. Folding only once the surface is set keeps the omelet tender and intact.

Swap the parsley

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

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

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