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 ↓
Macaroni Au Gratin
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.
Cook the macaroni
Boil the macaroni in the milk until tender.
Assemble the dish
Pour off the milk and mix the macaroni with seasoning, 8 ounces of grated cheese, and 4 ounces of butter in a stewpan.
Transfer the mixture to a deep or shallow pie dish.
Grate a little nutmeg over the top and lightly cover with breadcrumbs.
Bake and serve
Bake in a hot oven at 400°F (200°C) until browned and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk and structure of the dish, holding the sauce and cheese.
- Butter
- Adds richness and helps the cheese coat the pasta smoothly.
- Grated cheese
- Melts into a savoury sauce and browns on the surface.
- Breadcrumbs
- Form a crisp, browned topping over the pasta.
The step that matters
Bake until just browned. A hot oven browns the breadcrumbs and melts the cheese quickly. Overbaking dries the pasta and can cause the butter to separate from the cheese, leaving the dish greasy and tough.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, cheese, milk):
- Cinnamonfits about as well
- Nutmegthe original
- Thymefits about as well
- Pepperfits less well
Fit is the average pairing score against butter, cheese, milk. Candidates are from the same food group and used in at least 100 recipes.
