Why it works: Bread and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 11,466 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Escalloped Onions
Ingredients
Directions
The book says “a good 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.
Separate the onions with a large spoon.
Assemble and bake
In a pudding dish, layer the onions and grated bread crumbs alternately.
Season with pepper and coarse sea salt.
Moisten the layers with milk.
Bake in the oven until browned 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
- Become soft and sweet as they cook, forming the bulk of the dish.
- Grated bread crumbs
- Absorb moisture and help hold the layers together while baking.
- Milk
- Moistens the layers, adding moisture and richness as the dish bakes.
The step that matters
Moisten the layers with milk. Too little milk leaves the bread crumbs dry and the dish stiff, while too much makes it soggy. Adding it between layers lets the crumbs soak up liquid evenly as they bake.
Swap the onion
How well each one fits the dish's main ingredients (bread, pepper, milk):
- Capsicumfits better
- Tomatofits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against bread, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
