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, then a layer of cheese, a layer of butter, and a thick layer of beef hash.
Repeat the layers as needed.
Pour the milk over the top and bake at 350°F (175°C) until brown.

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.
- Cheese
- Melts into the layers and browns on top, adding richness and savory flavor.
- Beef hash
- Supplies the meaty, savory filling that gives the casserole its main flavor.
- Milk
- Adds moisture that soaks into the pasta and helps the casserole become creamy as it bakes.
- Butter
- Adds fat and richness that carries flavor through the layers and aids browning.
The step that matters
Pour the milk over the top and bake until brown. Milk poured over the layers needs time in the oven to soak into the pasta and set, while the surface browns. Pulling it too early leaves the casserole wet and underset, and baking too long can dry it out.
“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.
