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 ↓
Baked Peppers
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
Cut off the stem end of the peppers and remove the seeds and thick partitions.
Soak the peppers in salted water for 12 hours or briefly boil them until heated, then drain.
Stuff and bake
Mix the chopped meat, diced tomato, salt, melted butter, and rice together.
Stuff the mixture into the peppers and place them in a baking pan.
Add the onion slice, 1 tablespoon of butter, the tomato juice, and enough water to reach half the height of the peppers.
Bake at 300°F (150°C) for 1 hour, basting every 15 minutes.
Serve
Transfer the peppers to a serving dish, thicken the pan juices, pour over the peppers, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Absorbs liquid and cooks into the filling, giving it body and bulk.
- Cooked meat
- Adds savory flavour and richness to the rice filling.
- Butter
- Adds fat for richness and helps the filling and pan juices taste rounded.
- Tomato
- Adds acidity and moisture to the filling and the pan juices.
- Green peppers
- Hold the filling as edible shells that soften as they bake.
The step that matters
Soaking or boiling the peppers before stuffing. Raw peppers stay firm and can taste bitter, so softening them first helps them become tender during baking and keeps the filling from cooking unevenly.
Swap the onion
