Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and fat, and help the omelet set smooth and tender.
- Egg whites
- Beaten to foam, they trap air and give the omelet its light, airy structure.
- Sugar
- Sweetens the batter and helps the yolks blend into a smooth mixture.
- Butter
- Greases the pan and adds flavor and browning to the omelet's surface.
- Rum
- Adds aroma and a touch of flavor to the batter.
The step that matters
Gently fold in the beaten egg whites. Stirring or deflating the whites knocks out the air they hold, which makes the omelet dense instead of light and fluffy.
