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 ↓
Cheese Sauce
Ingredients
Directions
The book says “a hot oven”. The 400°F 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 stir to form a smooth paste.
Gradually add the scalded milk while beating constantly.
Add the salt, pepper, cayenne, and cheese.
Continue stirring until the cheese is melted.
Bake and serve
Pour over macaroni or transfer to a buttered baking dish.
Cover with breadcrumbs and bake in a hot oven (400°F / 200°C) until the crumbs are browned.

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 forming the roux base.
- Flour
- Thickens the sauce by forming a roux with the butter.
- Milk
- Forms the liquid body of the sauce, which thickens as it is added to the roux.
- Cheese
- Provides the main flavour and, once melted, gives the sauce its richness.
The step that matters
Gradually add the scalded milk while beating constantly. Adding the milk slowly while stirring keeps the flour paste smooth. Lumps form if the liquid goes in too fast, and the sauce cannot be fully smoothed afterward.
“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.
