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

What each ingredient does

Potato
Provides starch and moisture, giving the omelet a soft, light body.
Eggs
Whites trap air for lift when whisked; yolks add richness and help bind the mixture.
Butter
Adds fat for frying and browning and a rich flavor to the omelet's surface.

The step that matters

Folding in the egg whites. Whites whisked until stiff hold air that gives the omelet its lift. Folding gently preserves that air; stirring or deflating the mixture makes the omelet dense and flat.

Swap the potato

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