Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stuffed Peppers
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
Remove the stem end and seeds from the peppers.
Parboil the peppers in boiling water for 10 minutes.
Drain thoroughly, turning them upside down to dry.
Stuff and bake
Prepare a stuffing with stale bread crumbs and seasonings, adding enough boiling water to moisten well.
Fill the peppers with the stuffing.
Bake in a moderate oven at 350°F (175°C) for 25 to 30 minutes.
Serve
Serve with or without toast and Brown sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bell peppers
- Form the edible shell that holds the stuffing and softens during cooking.
- Stale bread crumbs
- Absorb moisture and give the stuffing body so it holds together in the pepper.
- Chopped meat
- Adds savory richness and substance to the stuffing filling.
The step that matters
Drain the peppers thoroughly. Water left on the parboiled peppers dilutes the stuffing and makes the filling soggy during baking. Turning them upside down lets excess liquid run off before filling.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, pepper, bread):
- Capsicumfits better
- Tomatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against meat, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
