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 Bell Peppers, American Style
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Slice off the tops of the bell peppers and scoop out the seeds.
Make the filling
In a saucepan, melt the butter and lightly fry the chopped onions.
Add the chopped mushrooms and cover the saucepan until moisture is reduced.
Stir in the reduced Allemande sauce, bread crumbs, salt, pepper, and nutmeg.
Remove from heat and mix in the egg yolks and parsley.
Stuff and bake
Stuff the mixture into the prepared bell peppers and place them in a buttered baking pan.
Sprinkle additional bread crumbs on top and add a small piece of butter on each.
Bake until nicely browned, then serve with a teaspoon of veal gravy over each pepper.

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 hollow edible shell that holds the filling during baking.
- Egg yolks
- Bind the filling and set when baked, giving it a firm, sliceable texture.
- Reduced allemande sauce
- Adds moisture and a rich, creamy body to the filling.
- Bread crumbs
- Absorb moisture and give the filling body, while the topping crisps and browns.
- Butter
- Adds fat and richness, and helps the topping brown in the oven.
The step that matters
Cover the mushrooms until their moisture is reduced. Mushrooms release a lot of water as they cook. If it is not cooked off before mixing, the filling becomes soggy and loose, and it may not hold together when baked with the egg yolks.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, mushroom, sauce, bread, nutmeg, egg):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against pepper, butter, mushroom, sauce, bread, nutmeg, egg. Candidates are from the same food group and used in at least 100 recipes.
