Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main bulk and moisture, softening into a pulp that flavors the eggs.
- Eggs
- Set when heated, thickening the tomato mixture into a soft, spoonable texture.
- Butter
- Adds richness and fat, helping the mixture cook smoothly in the pan.
The step that matters
Stirring the mixture over the heat until thick. Eggs set quickly and can curdle or turn grainy if overheated. Gentle, constant stirring over moderate heat keeps the proteins tender and the mixture smooth.
