Why it works: Butter and milk 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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Break macaroni into 1-inch lengths.
Boil macaroni in water for 15 minutes.
Assemble
Butter a baking dish and layer the macaroni.
Dot each layer with butter and sprinkle with pepper and mustard.
Sprinkle 1 tablespoon of cheese on each layer, using 2 tablespoons for the top layer.
Bake
Pour milk over the dish and bake at 400°F (200°C) for 20 minutes.

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 casserole and gives it its body.
- Butter
- Adds richness and helps keep the layers moist as they bake.
- Cheese
- Melts into the layers, adding savoury flavour and a rich texture.
- Milk
- Moistens the pasta and sets with the cheese into a creamy sauce as it bakes.
