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 a light texture, and yolks add richness and help the omelette set.
- Milk
- Adds moisture and makes the omelette tender as it cooks.
- Flour
- Gives the mixture structure so it holds together when set.
- Butter
- Adds fat for flavor and helps prevent sticking in the skillet.
The step that matters
Gently fold in the beaten egg whites. Egg whites hold air bubbles that make the omelette light. Stirring or mixing vigorously knocks out those bubbles, leaving a dense, flat result.
“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.
