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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the onions
Boil the onions for 1 hour and let them cool.
Cut a piece from the center of each onion with a sharp knife.
Fill and bake
Mix the chopped ham, stale bread crumbs, melted butter, cream or milk, salt, and cayenne together.
Fill the cavities of the onions with the mixture.
Sprinkle with buttered cracker crumbs and bake at 300°F (150°C) for 30 minutes.
Serve with white sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Hold the filling as edible cups and provide the main body and sweet flavor of the dish.
- Stale bread crumbs
- Absorb the butter and cream, giving the filling body and a soft, moist texture.
- Melted butter
- Adds fat for richness and carries flavor through the filling.
- Cream or milk
- Adds moisture so the bread crumbs soften into a spoonable filling.
- Chopped ham
- Contributes savory, salty flavor to the filling.
The step that matters
Cut a piece from the center of each onion. Removing too little leaves no room for the filling, while cutting too deep can break the onion wall and let filling leak out during baking. Boiling first softens the layers so they cut and fold cleanly.
Swap the onion
How well each one fits the dish's main ingredients (ham, bread, butter, cream, pepper):

Fit is the average pairing score against ham, bread, butter, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
