Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Beef Hash with Spaghetti
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
Cook the spaghetti according to package instructions, then wash and drain it.
Assemble and bake
In a baking pan, layer the spaghetti, cheese, and butter, adding a thick layer of beef hash between the layers.
Pour the milk over the layers.
Bake in a 350°F (175°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spaghetti
- Forms the bulk and structure of the casserole, holding the layers together as it bakes.
- Cheese
- Melts into the layers, adding richness and helping bind the casserole together.
- Milk
- Adds moisture that soaks into the layers and keeps the casserole from drying out.
- Butter
- Adds fat for richness and helps the top brown in the oven.
- Beef hash
- Provides the savory, meaty filling between the layers.
The step that matters
Bake until browned. Baking long enough lets the cheese melt and the top brown, which develops flavor through browning. Stopping too early leaves the casserole pale and loose, while over-baking can dry out the milk-soaked layers.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
