Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Tomatoes on Toast
Ingredients
Directions
Prepare the tomatoes
Skin the tomatoes and slice them.
Dredge the slices with flour, salt, and pepper.
Fry and assemble
Fry the tomatoes slowly in hot butter for about 10 minutes.
Carefully lift them out with a cake-turner and place on toasted bread.
Make the gravy and serve
In the pan, add butter, flour, and milk or cream to the gravy.
Cook for a few minutes, season lightly, and pour over the tomatoes and toast.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and juicy, slightly acidic flavour of the dish.
- Flour
- Coats the tomatoes and thickens the butter and milk into a gravy.
- Butter
- Fat for frying that adds richness and browning to the tomatoes and gravy.
- Milk or cream
- Adds moisture and body to the gravy, making it smooth and creamy.
The step that matters
Fry the tomatoes slowly in hot butter. Frying slowly lets the tomato slices cook through and brown gently without burning the butter or the flour coating. Careful heat control also keeps the slices intact when they are lifted out.
Swap the tomato
How well each one fits the dish's main ingredients (flour, pepper, butter, bread, milk):
- Capsicumfits better
- Potatofits better
- Shallotfits about as well
- Tomatothe original
Fit is the average pairing score against flour, pepper, butter, bread, milk. Candidates are from the same food group and used in at least 100 recipes.
