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 and Cheese
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the macaroni
Break macaroni into 1-inch pieces.
Cook in a large pot of boiling salted water until tender.
Drain in a colander and rinse with cold water.
Make the cheese sauce
In a saucepan, melt butter and stir in flour to make a roux.
Gradually add milk, stirring until thickened.
Add cheese and stir until melted.
Combine macaroni with cheese sauce and mix well.
Bake and serve
Transfer to a buttered baking dish and top with breadcrumbs.
Bake in a hot oven (400°F / 200°C) until brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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.
- Flour
- Thickens the butter and milk into a smooth roux-based sauce.
- Milk
- Forms the liquid base of the sauce, giving it creaminess.
- Cheese
- Melts into the sauce, adding richness and savory flavor.
- Butter
- Adds fat and flavor and helps form the roux with the flour.
- Breadcrumbs
- Form a crisp, browned topping in the oven.
The step that matters
Gradually add milk, stirring until thickened. Adding milk slowly to the hot roux while stirring lets the starch disperse evenly. Adding it all at once can create lumps that are hard to smooth out.
“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.
