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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Remove the pulp and seeds from the tomatoes.
Stuff and bake
Grind the pork or beef and mix with chopped onion, bread crumbs, beaten eggs, sage, salt, and paprika.
Stuff the mixture into the tomatoes.
Sprinkle the tops with bread crumbs and place a small piece of butter on each.
Bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork or beef
- Provides the main filling body and savory flavor once cooked through.
- Eggs
- Bind the filling so it holds together when sliced and served.
- Bread crumbs
- Absorb moisture and add body to the filling, and brown on top.
- Onion
- Adds savory sweetness and aroma to the meat filling.
- Butter
- Adds fat that melts over the tops, promoting browning and richness.
The step that matters
Removing the pulp and seeds. Scooping out the pulp leaves a sturdy tomato shell for the filling. Scooping too deeply can puncture the walls, letting juice leak and the filling collapse during baking.
Swap the sage
How well each one fits the dish's main ingredients (tomato, pork, onion, bread, egg, butter):
- Garlicfits better
- Thymefits better
- Parsleyfits better
- Sagethe original
Fit is the average pairing score against tomato, pork, onion, bread, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
