Why it works: Cheese and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Macaroni Cheese 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
Boil the macaroni in salted water until tender, then drain.
Assemble
In a greased pie dish, layer macaroni, sprinkle with cheese and seasonings, and repeat layers.
Mix breadcrumbs with the last layer of cheese.
Dot the top with small pieces of butter.
Bake and serve
Bake in a 400°F (200°C) oven until hot and browned on top.
Serve very hot with dry toast or plain biscuits.

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 sets the structure once layered and baked.
- Grated cheese
- Melts into the layers to give a rich, binding texture and savoury flavour.
- Breadcrumbs
- Form a crisp topping that browns in the oven, contrasting the soft interior.
- Butter
- Adds fat that enriches flavour and helps the top brown as it melts.
The step that matters
Bake until hot and browned on top. Baking must be long enough to heat the centre through and melt the cheese, while the breadcrumbs and butter brown the surface. Stopping early leaves the dish lukewarm and pale.
“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.
