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 give the dish its creamy, scrambled texture.
- Tomatoes
- Provide moisture and acidity that give the scramble its sauce-like body and tang.
- Butter
- Adds fat and richness and helps the eggs cook gently without sticking.
- Sugar
- Balances the acidity of the tomatoes with a touch of sweetness.
The step that matters
Cook until creamy, scraping the bottom of the pan. Egg proteins set quickly over direct heat. Constant scraping keeps curds moving and prevents overcooked, dry or stuck bits, so the eggs stay soft and creamy.
Swap the onion
How well each one fits the dish's main ingredients (tomato, sugar, butter, pepper, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against tomato, sugar, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
