Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large firm tomatoes
- Form the main body of the dish; firmness holds their shape under broiling.
- Hot butter
- Carries the seasonings and adds richness and moisture to the tomatoes.
- Made mustard
- Adds sharp, tangy flavour that balances the sweetness of the sugar.
- Sugar
- Adds sweetness and helps the surface brown under the broiler.
The step that matters
Broil the tomatoes until just cooked. Broiling too long collapses the tomato flesh and releases its juices, leaving the slices watery and soft. Brief high heat softens them while keeping their shape and letting the surface caramelise slightly.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, sugar, mustard):
- Horseradishfits better
- Capsicumfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against butter, pepper, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
