Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Stuffed 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
Wash and remove the centers from the bell peppers.
In a bowl, combine bread crumbs, chopped onion, chopped tomatoes, salt, pepper, and melted butter.
Fill the peppers with the stuffing mixture.
Bake and serve
Place the stuffed peppers closely together in a baking pan half-filled with hot water, adding a little soup stock or gravy if desired.
Cover the pan with another pan and bake at 350°F (175°C) for about 30 minutes.
Remove the cover for the last 5 to 10 minutes to allow the peppers to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread crumbs
- Form the bulk of the stuffing and soak up moisture from the vegetables and butter.
- Bell peppers
- Act as the edible shell that holds the stuffing and softens as it bakes.
- Butter
- Adds richness and fat that keeps the stuffing moist and helps it brown.
- Tomatoes
- Add moisture and acidity that give the stuffing a fresh, bright flavor.
- Onion
- Adds savory aroma and flavor to the stuffing as it cooks.
The step that matters
Covering the pan, then uncovering it to brown. Covering the pan traps steam so the peppers soften through without drying out. Removing the cover at the end lets dry heat brown the surface.
Swap the onion
How well each one fits the dish's main ingredients (pepper, bread, tomato, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Onionthe original
Fit is the average pairing score against pepper, bread, tomato, butter. Candidates are from the same food group and used in at least 100 recipes.
