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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sauce
Boil the macaroni until tender, then drain.
In a double boiler, heat the milk.
In a separate bowl, rub together the butter and flour, then add to the boiling milk.
Stir until the mixture thickens, then add salt and cayenne.
Stir in the grated cheese until melted.
Assemble and bake
Place the drained macaroni in a baking dish and pour the cheese sauce over it.
Mix the bread crumbs with melted butter and sprinkle on top.
Bake in a 350°F (175°C) oven for about 15 minutes, until the crumbs are golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and holds the sauce in its tubes and curves.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats.
- Butter
- Adds richness and, with flour, forms the roux that thickens the sauce.
- Flour
- Thickens the milk into a smooth sauce when cooked with butter.
- Grated cheese
- Melts into the sauce, adding savory flavor and a creamy texture.
- Dried bread crumbs
- Form a crisp topping that browns in the oven.
The step that matters
Thickening the white sauce. Add the butter-flour mixture to hot milk and stir constantly until it thickens. Lumps form if flour is not dispersed, and the sauce only thickens fully once it reaches a simmer.
