Why it works: Bread and butter 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 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
Boil the white onions in slightly salted water for one hour, changing the water twice.
Lift them out and scoop out a portion from the center.
Stuff and wrap
Fill the cavity with the bread crumbs, grated cheese, a little cream, salt, pepper, and the vegetables from the scooped-out onion.
Wrap each onion in a piece of buttered tissue paper and twist the ends securely.
Bake and serve
Bake in a buttered pan at 350°F (175°C) for nearly one hour.
Remove the paper, place in a deep dish, sprinkle with salt and pepper, and pour over melted butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White onions
- Form the edible shell that holds the stuffing and softens as it cooks.
- Bread crumbs
- Absorb the cream and add body to the stuffing.
- Grated cheese
- Melts into the stuffing, adding richness and savory flavor.
- Cream
- Moistens the stuffing so it stays tender rather than dry.
- Vegetables from the scooped-out onion
- Add onion flavor and texture to the filling, using the removed centre.
The step that matters
Boiling the onions in changed water. Boiling softens the onions and mellows their sharp sulfur compounds, so they can be scooped without tearing and the finished onion tastes milder.
Swap the onion
How well each one fits the dish's main ingredients (bread, cheese, cream, pepper, butter):
- Potatofits about as well
- Capsicumfits about as well
- Onionthe original
- Tomatofits about as well
Fit is the average pairing score against bread, cheese, cream, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
