Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into soft curds that bind the tomatoes and cheese together.
- Butter
- Fats the pan and carries flavour while the tomatoes fry.
- Grated cheese
- Melts into the eggs, adding richness and a savoury, binding texture.
- Tomatoes
- Provide moisture and acidity that give the mixture its fresh, juicy character.
The step that matters
Stir quickly and add the cheese. Eggs set quickly over direct heat, so stirring keeps them in soft curds rather than letting them turn rubbery or scramble unevenly while the cheese melts in.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter, cheese, pepper):
- Capsicumfits better
- Asparagusfits better

- Tomatothe original
Fit is the average pairing score against egg, butter, cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
