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 a LA Royale
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook the pasta
Cook the macaroni in boiling salted water until al dente.
Drain the macaroni and set aside.
Make the sauce
Melt butter in a saucepan over medium heat.
Stir in flour to make a roux.
Gradually add milk, stirring constantly until the sauce thickens.
Add cheese, salt, and pepper to the sauce, stirring until the cheese melts.
Assemble and bake
Combine the macaroni with the cheese sauce and mix well.
Transfer the mixture to a baking dish.
Bake at 350°F (175°C) until golden and bubbly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Provides the bulk and starchy body that the sauce coats and holds together.
- Butter
- Adds fat and richness, and forms the base of the roux that thickens the sauce.
- Cheese
- Melts into the sauce to give a creamy texture and savoury flavour.
- Milk
- Forms the liquid that the roux thickens into a smooth, creamy sauce.
The step that matters
Add the milk gradually while stirring constantly. Flour starch thickens the sauce as it heats in liquid. Adding milk slowly and stirring keeps the starch evenly dispersed, which prevents lumps and gives a smooth sauce.
