Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Provides the base that holds the toppings and becomes crisp when toasted.
- Butter
- Adds fat and richness that carries flavour across the toast.
- Lemon juice
- Adds acidity that brightens the sweet and savoury toppings.
- Sugar
- Adds sweetness and helps the top brown lightly when heated.

- Figfits about as well
- Plumfits less well
- Mangofits less well
Fit is the average pairing score against bread, pepper, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
