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 ↓
Stuffed Bell Peppers
Ingredients
Directions
The book says “a hot oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the peppers
Cut off the tops of the bell peppers and remove the seeds.
In a skillet, fry the chopped onion in butter until soft.
Fill and stuff
In a bowl, mix the fried onion, hot boiled rice, and hamburger.
Stuff the mixture into the prepared bell peppers.
Place the stuffed peppers upright in a baking dish.
Bake and serve
Cover the peppers with their tops and lay a slice of bacon on each.
Pour the can of tomatoes over the stuffed peppers.
Bake in a 300°F (150°C) oven for 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hamburger
- Provides the meaty filling and savory flavor that the rest of the stuffing is built around.
- Hot boiled rice
- Absorbs juices and fat from the meat, giving the filling bulk and a softer texture.
- Bell peppers
- Act as edible containers that soften during baking and hold the filling in shape.
- Bacon
- Renders fat over the peppers as they bake, adding moisture and savory flavor to the tops.
- Tomatoes
- Add acidity and liquid that moisten the filling and blend into a sauce during the long bake.
The step that matters
Bake at a low temperature for a long time. Baking at 300°F for 3 hours lets the peppers soften fully and the meat cook through gently, so the filling stays moist rather than dry or tough.
Swap the onion
How well each one fits the dish's main ingredients (pepper, rice, butter, tomato):
- Capsicumfits better

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