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 Onions
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 onions
Parboil large onions in salted boiling water for 10 minutes.
Cool and remove the centers of the onions.
Make the filling
Mash the centers and mix with chopped cold meat, bread crumbs, and enough cream or melted butter to moisten.
Season the mixture with salt and pepper.
Fill the onion shells with the mixture.
Bake
Place in a buttered shallow baking pan and bake at 350°F (175°C) until the onions are tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large onions
- Form the edible shells that hold the filling and soften during baking.
- Stale soft bread crumbs
- Absorb moisture and bind the filling so it holds its shape.
- Cream or melted butter
- Moistens the filling and adds richness so it does not dry out.
- Cold meat
- Provides the savoury body and bulk of the filling.
The step that matters
Parboiling the onions. Parboiling softens the onions enough to be hollowed without tearing and begins cooking them, so they become tender in the oven. Cooling before hollowing keeps the shells firm enough to handle.
Swap the onion
How well each one fits the dish's main ingredients (meat, bread, cream, pepper):
- Capsicumfits better
- Spinachfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against meat, bread, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
