Why it works: Butter and bread 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.
Make the filling
In a skillet, brown the chopped onions and chilis in butter.
Add the chopped tomatoes and cooked veal; cook until done.
Season with salt and pepper.
Stuff and bake
Fill the peppers with the mixture.
Top each pepper with a spoonful of bread crumbs and a lump of butter.
Bake at 400°F (200°C) for 15 to 20 minutes and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bell peppers
- Hold the filling and soften as they bake, becoming tender and sweet.
- Veal
- Provides the main cooked protein that gives the filling its body and savory flavor.
- Tomatoes
- Add moisture and acidity that blend with the filling as it cooks.
- Bread crumbs
- Form a crisp, golden topping that browns in the oven and absorbs surface butter.
- Butter
- Adds richness and fat, helping the onions brown and the topping crisp.
The step that matters
Cook the filling until done before stuffing. The veal is already cooked, and the peppers bake only briefly. Cooking the tomato and veal mixture first lets excess moisture evaporate, so the filling stays thick rather than making the peppers watery.
Swap the onion
How well each one fits the dish's main ingredients (butter, tomato, veal, pepper, bread):
- Capsicumfits better
- Potatofits about as well

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