Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main structure, and beaten whites and yolks give the omelet its light, set body.
- Milk
- Adds moisture and softness, keeping the omelet tender rather than dry.
- Butter
- Adds richness and flavor, and keeps the skillet surface from sticking.
- Flour
- Thickens the milk mixture so it holds together and sets with a smoother texture.
The step that matters
Cook slowly over low heat without stirring. High heat or stirring can toughen the proteins in the eggs and make the omelet rubbery or cause browning before the center sets. Gentle heat lets the egg set evenly into a tender layer.
