Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, moisture and acidity of the dish.
- Eggs
- Set when cooked, binding the mixture into a soft, tender body.
- Crumbled bread
- Absorbs liquid and thickens the tomato mixture as it cooks.
- Butter
- Adds richness and fat for a smoother, more rounded flavor.
- Onions
- Add savory aroma and sweetness as they soften in the mixture.
The step that matters
Stir the beaten eggs into the mixture and cook for a few minutes. Eggs set quickly under heat and can turn rubbery or curdle if overcooked. Stirring them in gently over moderate heat keeps them tender and evenly distributed through the tomato base.
Swap the onion
How well each one fits the dish's main ingredients (tomato, bread, butter, egg, pepper):
- Capsicumfits better
