Why it works: Bread and butter 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 ↓
Scalloped Tomatoes
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare and bake
Layer 1 cup of tomatoes and 1 cup of bread crumbs alternately in a small baking dish.
Spread 1 tablespoon of butter over the top.
Add ½ cup of water.
Bake in a 350°F (175°C) oven for about 30 minutes.
Make the sauce
Run the remaining 1 cup of tomatoes through a sieve into a small kettle.
Add the remaining water, 1 tablespoon of butter, sugar, and cayenne pepper to the kettle.
Boil for 1 minute, then remove from heat.
Serve
Serve the sauce hot with the baked tomatoes on individual dishes.

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 moisture, and their acidity is balanced by the sugar.
- Bread crumbs
- Soak up the tomato liquid and give the dish a soft, set texture.
- Butter
- Adds fat and richness, carrying flavour through the baked layers and the sauce.
- Sugar
- Adds sweetness that softens the sharpness of the tomatoes.
Swap the tomato
How well each one fits the dish's main ingredients (bread, pepper, butter, sugar, sauce):
- Capsicumfits better
- Mustardfits about as well
- Tomatothe original
- Shallotfits about as well
Fit is the average pairing score against bread, pepper, butter, sugar, sauce. 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.
