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 ↓
To Bake Tomatoes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Scald and peel the tomatoes.
Butter a shallow baking dish and arrange the whole tomatoes inside without breaking them.
Fill the spaces between the tomatoes with buttered stale bread.
Make the sauce
Mash the remaining tomatoes and strain out the hard parts.
Mix the strained tomatoes with butter, salt, and pepper.
Bake and serve
Pour the mixture over the tomatoes in the dish.
Strew bread crumbs on top and sprinkle sugar between each layer of tomatoes.
Bake at 350°F (175°C) for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Supply the main body and juice that softens into a sauce as they bake.
- Stale bread
- Soaks up tomato juice, giving the dish a soft, absorbent body.
- Bread crumbs
- Form a topping that browns and adds a crisp contrast to the soft tomatoes.
- Sugar
- Balances the sharp acidity of the tomatoes and encourages browning on top.
- Butter
- Adds fat for richness and helps the crumbs brown in the oven.
The step that matters
Arrange the whole tomatoes without breaking them. Whole tomatoes hold their shape while baking only if their skins stay intact and they are handled gently. Broken tomatoes release juice early, leaving a watery dish with less structure.
Swap the tomato
How well each one fits the dish's main ingredients (butter, bread, pepper, sugar):
- Capsicumfits better
- Potatofits about as well
- Sweet potatofits about as well
- Tomatothe original
Fit is the average pairing score against butter, bread, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
