Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm, tender structure as the mixture cooks.
- Potatoes
- Add body and a soft, starchy texture to the egg mixture.
- Milk
- Adds moisture and makes the eggs more tender and creamy.
- Bacon
- Contributes salty, savory fat and browned flavor.
- Butter
- Adds richness and helps the mixture brown in the pan.
The step that matters
Stir, then leave it alone. Stirring while the base begins to brown breaks up the forming curds and gives an even texture, but once the bottom has set, leaving it undisturbed lets it firm into one cohesive omelet without tearing or scrambling.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, milk, pepper, butter):
