Why it works: Tomato and rice 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 Green Peppers
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Remove seeds from the peppers and parboil them in cold water for a few minutes.
In a pot, cook the tomatoes, onion, and seasonings (butter, salt, pepper, and sugar) for about 30 minutes.
Add the cooked rice to the tomato mixture and stir well.
Stuff and bake
Fill the peppers with the rice mixture and place them in a buttered baking dish.
Add a small amount of water to the dish to prevent burning.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet peppers
- Their walls hold the filling and soften as they bake, becoming tender around the rice.
- Tomatoes
- Cooked down into a moist, acidic sauce that flavours the rice and keeps the filling from drying out.
- Onion
- Softens as it cooks, adding sweetness and savoury depth to the tomato base.
- Boiled rice
- Forms the bulk of the filling, absorbing the tomato juices and giving the dish body.
The step that matters
Adding water to the baking dish. A little water in the dish creates steam and keeps the pan from scorching, so the peppers cook through gently instead of burning on the bottom.
Swap the onion
How well each one fits the dish's main ingredients (pepper, tomato, rice, butter, sugar):

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