Why it works: Pepper and parsley 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 ↓
Stuffed Tomatoes
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the tomatoes
Wipe the tomatoes dry and cut off the tops to create hinged covers.
Scoop out the centers, leaving enough meat to form shells.
Make the filling
Mince and sauté the onion until golden, then add the tomato pulp and simmer for 20 minutes.
Season with butter, coarse sea salt, and Cayenne pepper.
Add enough bread crumbs to absorb the juice and mix in chopped parsley.
Bake and serve
Stuff the mixture into the tomato shells.
Arrange the stuffed tomatoes on an oiled baking pan.
Bake for 20 minutes at 300°F (150°C).
Serve on a fancy folded napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the edible shells and, once their pulp is cooked down, the moist base of the filling.
- Onion
- Adds savory sweetness and aroma as it browns in the sauté.
- Bread crumbs
- Absorb the tomato juice so the filling holds together rather than running out.
- Butter
- Adds fat and richness to the filling.
The step that matters
Adding the bread crumbs. Crumbs should soak up the juice only until the filling is moist but not loose. Too much juice makes the filling soggy and runny, while too few crumbs leave it wet and unable to hold its shape inside the shells.
Swap the onion
How well each one fits the dish's main ingredients (tomato, butter, pepper, bread, parsley):
- Capsicumfits better

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