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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the onions
Do not overcook the onions; keep them intact.
Stuff and bake
Remove the inner sections of the onions, chop them finely, and mix with the soft bread crumbs, meat, melted butter, salt, and pepper.
Refill the onions with the mixture and place them close together in a small buttered baking dish.
Pour the white sauce over the stuffed onions, sprinkle with the buttered crumbs, and bake for 30 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Form the edible shell that holds the stuffing and softens as it bakes.
- Soft bread crumbs
- Absorb moisture and bind the chopped onion and meat into a cohesive filling.
- White sauce
- Adds moisture and richness so the filling stays tender while baking.
- Buttered dry bread crumbs
- Toast in the oven to form a golden, crisp topping.
The step that matters
Do not overcook the onions before stuffing. Onions that are overcooked become soft and fragile, so they tear when refilled and cannot hold the stuffing. Keeping them intact preserves a sturdy shell that survives handling and baking.
Swap the onion
How well each one fits the dish's main ingredients (bread, meat, sauce, butter):
- Shallotfits better
- Tomatofits about as well
- Mustardfits about as well
- Onionthe original
Fit is the average pairing score against bread, meat, sauce, butter. Candidates are from the same food group and used in at least 100 recipes.
