Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Break down into a juicy, saucy topping that moistens the toast.
- Eggs
- Set when poached, adding richness and a runny yolk that blends with the tomatoes.
- Bread
- Provides a crisp, sturdy base that holds the sauce without going soggy.
- Butter
- Adds fat and flavor to the tomatoes and coats the toast.
- Sugar
- Balances the acidity of the tomatoes with a touch of sweetness.
The step that matters
Boiling the tomatoes for 10 minutes. Boiling reduces the tomatoes' water and concentrates their flavor, so the sauce thickens rather than spreading thin and soaking the toast. Keep the heat steady so the sauce thickens evenly.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, sugar, butter, bread, egg):
- Capsicumfits better
- Asparagusfits better
- Leekfits about as well
