Why it works: Butter and bread 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 ↓
Macaroni Au Gratin
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook the macaroni
In a pot, combine milk and water with nutmeg and salt; bring to a boil.
Add macaroni and cook until tender, then drain.
Assemble and bake
In a deep dish, layer macaroni and sprinkle some grated cheese on top.
Pour remaining cheese over the macaroni and dot with butter.
Sprinkle bread crumbs on top and bake at 400°F (200°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pipe macaroni
- Forms the bulk and structure of the dish, holding the sauce in its tubes.
- Cheese
- Melts into the milk to create a creamy, binding sauce and a savory flavor.
- Butter
- Adds richness and fat, helping the top brown as it bakes.
- Fresh milk
- Provides the liquid base that becomes the creamy sauce with the cheese.
- Bread crumbs
- Form a crisp, golden topping through browning in the oven.
The step that matters
Bake until golden brown. The bread crumbs and butter brown through dry heat, which gives the crust its color and flavor. Pulling the dish too early leaves the topping pale and the cheese sauce under-set, while overbaking can dry the macaroni.
Swap the nutmeg
How well each one fits the dish's main ingredients (cheese, butter, milk, bread):
- Cinnamonfits about as well
- Nutmegthe original
- Thymefits about as well
- Pepperfits less well
Fit is the average pairing score against cheese, butter, milk, bread. Candidates are from the same food group and used in at least 100 recipes.
