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 for 15 minutes.
Remove the center part, leaving two or three circles.
Fill and cook
Mix the chopped meat with the soaked bread crumbs, beaten egg, salt, and pepper.
Fill the onion shells with the mixture.
Brown the filled onions in a little butter.
Bake at 400°F (200°C) for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Provides the savoury filling that makes up the body of each stuffed onion.
- Bread crumbs
- Soaked in water, they absorb liquid and keep the filling moist and tender.
- Beaten egg
- Binds the meat and crumbs together so the filling holds its shape.
- Butter
- Adds fat that helps the onion surfaces brown and gives a rich flavour.
The step that matters
Remove the center part, leaving two or three circles.. Cutting too little leaves the shell thick and the filling hard to cook through, while cutting too much tears the layers and the filling leaks out. Keeping two or three intact rings gives a sturdy cup that holds the filling during cooking.
Swap the onion
How well each one fits the dish's main ingredients (meat, bread, egg, pepper, butter):
