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

What each ingredient does

Mashed potatoes
Provide the bulk and soft, creamy body of the omelet.
Eggs
Set during cooking to hold the omelet together, with whites adding lift from the folded foam.
Milk
Adds moisture and softness to the potato mixture.
Butter
Adds richness and helps keep the omelet from sticking to the pan.

The step that matters

Folding in the egg whites. Whites beaten to a foam trap air that gives lift; folding gently keeps that air in, while stirring hard would deflate the mixture and leave a dense omelet.

Swap the potato

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

  1. Capsicumfits about as well
  2. Potatothe original
  3. Asparagusfits about as well
  4. Chivefits less well

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