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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Cook the onion and mushrooms in butter for about 15 minutes.
Add salt and pepper to taste.
Prepare the peppers
Pour boiling water over the peppers.
Let the peppers stand for about 10 minutes.
Drain the peppers.
Stuff and bake
Stuff the peppers with the onion and mushroom mixture.
Sprinkle the tops with bread crumbs.
Bake at 400°F (200°C) for 15 minutes.
Serve with brown toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bell peppers
- Act as the edible shell that holds the filling and softens during cooking.
- Bread crumbs
- Form a crisp, browned topping over the stuffed peppers.
- Mushrooms
- Add savory, meaty bulk and moisture to the filling.
- Onion
- Adds sweetness and aroma to the filling as it cooks down in butter.
- Butter
- Carries the onion and mushrooms, adding richness and flavor to the filling.
The step that matters
Draining the peppers after boiling. Peppers left wet release extra water into the filling, diluting its flavor and making the bread crumb topping soggy rather than lightly browned. Drain them well before stuffing.
Swap the onion
How well each one fits the dish's main ingredients (bread, mushroom, butter, pepper):

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