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 ↓
Stuffed Tomatoes
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Slice the top off each tomato and scoop out the pulp.
Combine the ham, onion, and tomato pulp in a small saucepan.
Cook the mixture slowly with a lid for 10 minutes.
Season the mixture with salt, pepper, and cayenne.
Stir in the grated bread.
Add the beaten egg and stir until thickened, about 3 minutes.
Carefully fill the tomato shells with the mixture.
Make the paste and bake
Rub the butter into the flour and baking powder in a bowl.
Add water to form a firm paste.
Roll out the paste and line six patty pans.
Bake the paste until pale brown.
Assemble and serve
Place a stuffed tomato in three of the pans and pile the remaining mixture in the other three.
Warm in a hot oven (400 °F / 200 °C) for 2 minutes and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Hold the filling as shells and add juicy, slightly acidic flavour when warmed.
- Egg
- Sets with heat to bind the filling so it thickens and holds its shape.
- Flour
- Forms the structure of the paste that lines the patty pans.
- Butter
- Adds fat that short-textures the paste and helps it brown.
- Baking powder
- Releases gas during baking so the paste rises lightly and stays tender.
- Ham
- Provides savoury, salty meat flavour to the filling.
The step that matters
Add the beaten egg and stir until thickened. Egg proteins set when heated, so stirring over gentle heat thickens the filling evenly; if it boils hard or is overcooked, the egg can curdle and turn grainy.
Swap the onion
How well each one fits the dish's main ingredients (tomato, ham, bread, pepper, egg, flour, butter):
- Capsicumfits better

- Onionthe original
Fit is the average pairing score against tomato, ham, bread, pepper, egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
