Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set to form the body of the omelette as they cook.
- Flour
- Thickens the egg mixture and gives it a more stable, tender texture.
- Milk
- Adds moisture and softness to the egg mixture.
- Tomatoes
- Add moisture, acidity, and fresh flavour to the filling.
The step that matters
Cook until set and lightly browned. Eggs set through gentle heat and continued cooking. Too much heat toughens and dries them, while too little leaves the centre runny.
Swap the tomato
How well each one fits the dish's main ingredients (egg, flour, pepper, milk):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against egg, flour, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
