Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated, thickening the mixture into a soft, spreadable topping.
- Cheese
- Melts into the eggs, adding richness and savoury flavour.
- Tomatoes
- Add moisture and a fresh, slightly acidic flavour to the mixture.
- Butter
- Adds fat for flavour and helps keep the egg mixture from sticking to the pan.
The step that matters
Stir the egg mixture into the melted butter and heat until very hot, but not boiling. Eggs thicken as their proteins set with heat. Overheating or boiling makes them curdle and turn grainy and watery, so stop heating once the mixture is hot and thick.
