Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Stuffed Pepper
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 the pepper
Cut the top off the pepper and remove the seeds and membrane.
Slice a thin piece from the bottom so it can stand upright.
Make the white sauce
In a saucepan, melt 5 tablespoons of butter, then stir in 3 tablespoons of flour and ½ teaspoon of salt.
Gradually add 4 cups of milk, stirring until the mixture thickens to form a white sauce.
Add the chopped meat and onion juice to the sauce, mixing well.
Fill and bake
Fill the prepared pepper with the meat mixture and top with 1 tablespoon of buttered crumbs.
Place the pepper in a baking pan and add boiling water to the bottom.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavor while forming the roux base.
- Flour
- Thickens the milk into a white sauce that holds the meat together.
- Milk
- Forms the liquid base of the white sauce, giving it body and creaminess.
- Cooked veal or chicken
- Provides the main filling, adding protein and substance to the dish.
The step that matters
Stirring the milk into the roux. Adding the milk gradually while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (pepper, milk, butter, veal, flour):
- Potatofits better

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