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

What each ingredient does

Eggs
Yolks enrich and set the custard, while beaten whites add air and lift.
Milk
Provides the liquid base that gives the omelette moisture and a tender texture.
Butter
Adds fat for richness and flavor, and helps the mixture feel smooth.
Flour
Thickens the milk so the mixture holds its body during cooking.

The step that matters

Gently fold in the beaten egg whites.. The whites trap air that makes the omelette light. Stirring or mixing hard deflates those bubbles, so the result turns out dense and flat.
