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

What each ingredient does

Eggs
Whites trap air for lightness, while yolks enrich the omelet and help it set.
Water or milk
Adds moisture, so the omelet stays tender rather than dry.
Butter
Fat for frying that adds flavor and helps prevent sticking and browning.

The step that matters

Beat the yolks and whites separately until very light. Whipping the whites builds air bubbles that give the omelet its lift. Beating them separately from the yolks keeps those bubbles from collapsing before cooking, so the omelet stays light rather than dense.
