Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh tomatoes
- Provide the main moist topping that softens into a stewed, saucy layer.
- Butter
- Adds richness and fat, enriching both the tomatoes and the toast.
- Slices of bread
- Form the base that soaks up the tomato juices and holds the topping.
- Sugar
- Adds a little sweetness that balances the acidity of the tomatoes.
The step that matters
Stew the tomatoes until tender. Stewing softens the tomatoes and concentrates their flavour. If they are under-cooked, they stay watery and soak the bread unevenly, so cook until tender before topping.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, sugar, bread):
- Capsicumfits better
- Potatofits about as well
- Sweet potatofits about as well
- Tomatothe original
Fit is the average pairing score against butter, pepper, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
