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 add richness and set structure to the omelet.
- Flour
- Gives the batter body so the omelet holds its shape after cooking.
- Baking powder
- Releases gas in the batter, helping the omelet rise and stay light.
- Milk
- Adds moisture to the batter, keeping the omelet tender as it sets.
The step that matters
Fold in the egg whites gently. Beaten egg whites hold trapped air that gives the omelet its lift. Vigorous stirring knocks that air out, leaving a dense, flat result.
