Why it works: Rice and tomato match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,065 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Rice Stuffed Peppers
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).
In a bowl, mix the rice, egg, pork, onion, crumbs, salt, and peppers.
Wash the peppers, remove the ends and seeds, then stuff them with the mixture.
Bake
Place the stuffed peppers in a baking dish and pour the strained tomatoes over them.
Top each pepper with a thin slice of bacon.
Cover the dish and bake for 15 minutes.
Uncover and bake until well done and browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked rice
- Bulks out the filling and gives the stuffing a light, tender texture.
- Egg
- Binds the filling so it holds its shape when baked.
- Ground pork or beef
- Adds savory richness and fat that keeps the filling moist.
- Cracker or bread crumbs
- Absorb moisture and help the filling hold together.
- Tomatoes
- Provide moisture and acidity that cook into a sauce around the peppers.
- Bacon
- Renders fat over the peppers and adds smoky flavor and browning.
The step that matters
Covering, then uncovering the dish. Covering traps steam so the filling cooks through and the pepper softens; uncovering lets the surface brown and the sauce reduce. Skipping either stage leaves the peppers either underdone or pale and watery.
Swap the white pepper
How well each one fits the dish's main ingredients (rice, egg, pork, onion, bread, pepper, tomato):
- Garlicfits better
- Thymefits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against rice, egg, pork, onion, bread, pepper, tomato. Candidates are from the same food group and used in at least 100 recipes.
