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

What each ingredient does

Eggs
Set into the structure of the omelet as they cook, holding it together.
Butter
Adds richness and helps the omelet brown lightly in the hot pan.
Milk or cream
Adds moisture and softness, keeping the omelet tender rather than dry.

The step that matters

Stir until it begins to set, then stop stirring. Stirring while the eggs set breaks up forming curds, giving a smoother texture. Once the edges firm up, leaving the base still lets the underside brown evenly without tearing the omelet.

Swap the potato

The recipe marks potato as optional. How well each one fits the dish's main ingredients (egg, butter, bread, flour, rice, pepper, nutmeg):

  1. Shallotfits better
  2. Spinachfits better
  3. Leekfits better
  4. Potatothe original

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