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

What each ingredient does

Eggs
Whites trapped in foam and set proteins give the omelette its light, risen structure.
Milk
Adds moisture and softness, so the custard-like interior stays tender rather than dry.
Butter
Melted fat in the hot dish helps the base brown and release cleanly, adding richness.
Arrowroot
Starch that thickens the yolk mixture slightly, helping it hold its shape when baked.

The step that matters

Mix the yolks and whites together quickly. Folded egg white foam loses air if it sits or is overworked, and the omelette will not rise well. Combine promptly and then get the mixture into the hot oven.

Swap the arrowroot

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

  1. Carrotfits better
  2. Potatofits better

  4. Arrowrootthe original

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