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.
Prepare the macaroni
Boil the macaroni until done, then cut it into three-inch lengths.
Make the mixture
Combine the macaroni, grated Parmesan cheese, fresh butter, béchamel sauce, pepper, and salt in a stewpan.
Toss the mixture over low heat until well mixed.
Bake and serve
Arrange fried croutons around the bottom of a baking dish and pile the macaroni mixture in the center.
Sprinkle the top with equal parts bread crumbs and grated Parmesan cheese.
Drizzle melted butter over the macaroni.
Bake in a 400°F (200°C) oven until the top is bright yellow and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parmesan cheese
- Adds savory, salty flavor and helps form a golden, browned crust on top.
- Fresh butter
- Adds richness and fat, giving the mixture a smooth, silky texture.
- Béchamel sauce
- Coats the macaroni and binds it into a creamy, moist mixture.
- Macaroni
- Forms the bulk of the dish, providing its body and chewy structure.
The step that matters
Toss the mixture over low heat. Gentle heat lets the cheese and sauce coat the pasta evenly without melting the cheese into greasy clumps or scorching the bottom of the pan.
