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

What each ingredient does

Eggs
Set into a structure that holds the potatoes together as the omelette cooks.
Potatoes
Provide the bulk and browned, starchy texture that fills the omelette.
Butter
Adds richness and helps the potatoes brown without sticking to the skillet.

The step that matters

Add the eggs when the potatoes are browned and let them set gently. Eggs cook quickly and turn rubbery if the heat is too high. Medium heat lets the proteins set slowly into a tender layer, and folding only once they begin to set keeps the omelette soft.

Swap the potato

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

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