Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the soft structure of the omelet rolls as they cook.
- Milk
- Adds moisture so the eggs stay tender rather than dry and rubbery.
- Tomatoes
- Provide the main body and acidity of the sauce once cooked and pureed.
- Butter
- Adds fat and richness to the seasoned tomato sauce.
- Sugar
- Adds a touch of sweetness that balances the tomatoes' acidity.
The step that matters
Cooking the egg mixture in the skillet. Eggs cooked over high heat toughen and turn rubbery as proteins tighten and squeeze out water. Gentle heat keeps the rolls soft and moist.
Swap the tomato
How well each one fits the dish's main ingredients (egg, milk, butter, pepper, sugar):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against egg, milk, butter, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
