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

What each ingredient does

Eggs
Set to form the structure of the omelette as they cook.
Butter
Fats the pan so the egg mixture cooks without sticking and adds richness.
Parsley
Adds a fresh, green herbal aroma to the eggs.
Oysters
Add a briny, savoury flavour to the oyster variation.

The step that matters

Cook until set, then fold the omelette in half. Cooking over heat only until the egg is set keeps the omelette tender. Overcooking tightens the proteins, making it dry and rubbery, and folding too early can tear the still-liquid centre.

Swap the nutmeg

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

  1. Capersfits better
  2. Nutmegthe original
  3. Celeryfits about as well
  4. Tarragonfits about as well

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