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 lift, and yolks set into the structure as the mixture cooks.
- Milk
- Provides the liquid base that cooks into a tender, custard-like body.
- Flour
- Thickens the liquid and gives the omelet body so it holds together.
- Butter
- Adds richness and helps keep the mixture from sticking to the pan.
The step that matters
Fold in the beaten egg whites gently. Beaten whites hold air bubbles that give lift. Stirring vigorously knocks that air out, leaving a dense, flat result, so the whites should be folded in with slow, sweeping strokes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
