Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
White Sauce for Macaroni
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
Melt the butter in a saucepan.
Add the flour and salt, stirring until combined.
Gradually add the hot milk, stirring continuously until the sauce thickens.
Assemble and bake
Add cooked macaroni and cheese to the sauce, mixing well.
Transfer the mixture to a baking dish and cover the top with bread crumbs.
Bake in a moderate oven at 350°F (175°C) until the crumbs are brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while helping the roux form.
- Flour
- Thickens the milk into a smooth sauce that holds the pasta together.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats with the flour.
- Macaroni
- Provides the body of the dish, absorbing sauce and setting in the baked casserole.
- Cheese
- Adds richness and savoury flavour, and melts into the sauce for creaminess.
- Bread crumbs
- Forms a topping that browns in the oven for crunch and contrast.
The step that matters
Stirring the milk into the butter and flour. Adding the hot milk gradually while stirring constantly keeps the starch evenly dispersed. Lumps form if the liquid is added too fast or stirring stops, and the sauce may not thicken smoothly.
