Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelette as they heat, forming its body.
- Cold water
- Adds moisture, so the omelette stays tender rather than dry and rubbery.
- Butter
- Fat for the pan that prevents sticking and adds rich flavour and light browning.
- Onion
- Adds savoury, aromatic flavour to the eggs.
The step that matters
Stir the eggs until they just firm up. Eggs set quickly from the edges inward. Stirring keeps the curds small and soft, while letting them sit too long makes the omelette tough and dry.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, onion, parsley, butter):
- Capersfits better
- Thymefits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against egg, onion, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
