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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Boil the onions until tender.
Remove the centers and chop them.
Mix the chopped centers with the ham, bread crumbs, nut meats, salt, and pepper.
Stuff the onion shells with the mixture.
Bake
Place a small piece of butter on top of each stuffed onion.
Bake for 25 minutes at 400°F (200°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 shells that hold the stuffing and soften when boiled.
- Boiled ham
- Adds savory, meaty flavor and some chew to the filling.
- Bread crumbs
- Absorb moisture and bind the chopped onion and ham into a stuffing.
- Nut meats
- Add crunch and a toasty, nutty flavor to the filling.
- Butter
- Adds richness and helps the tops brown as they bake.
The step that matters
Boil the onions until tender. Onions must be fully softened before stuffing, because raw or firm onion shells stay tough and will not cook through in the time given for baking.
