Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked 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 the tomatoes
Preheat the oven to 350 °F (175 °C).
Cut a round opening in the center of each tomato and scoop out the seeds and soft part with a teaspoon.
Season the stale bread crumbs with minced onion, parsley, coarse sea salt, and black pepper.
Fill the tomatoes with the seasoned bread crumbs.
Bake
Butter a baking pan and place the tomatoes close together.
Dot the tops of the tomatoes with a few bits of butter and add a little water to the bottom of the pan.
Bake in the preheated oven.
If the tomatoes start to scorch, cover them with buttered paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large firm tomatoes
- Hold the filling and soften into tender, juicy shells as they bake.
- Stale bread crumbs
- Absorb juices and form a soft, savory filling that holds its shape.
- Butter
- Adds richness and helps the tops brown while coating the pan.
The step that matters
Covering the tops if they scorch. Tomato sugars and butter brown quickly in dry oven heat, so the tops can burn before the centers are tender. Covering with buttered paper slows browning while the interior keeps cooking.
Swap the onion
How well each one fits the dish's main ingredients (tomato, bread, parsley, pepper, butter):
- Capsicumfits better
- Carrotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against tomato, bread, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
