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 Francaise
Ingredients
Directions
The book says “a slack oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cook the macaroni in boiling water for 20 minutes, then drain.
In a 3-quart baking dish, combine the macaroni, diced cheese, and butter.
Make the custard and sauce
Mix the eggs, milk, and a tablespoon of flour together, then pour over the macaroni.
While baking, prepare a pint of cream sauce, adding a tablespoon of chopped parsley.
Bake and serve
Bake in a 400°F (200°C) oven.
Pour the cream sauce over the macaroni and bake until light brown on top.
Serve in the baking dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and holds the custard and sauce together.
- Eggs
- Set when baked, giving the gratin structure and a custard-like texture.
- Milk
- Combines with the eggs to form a custard that keeps the gratin moist.
- Cheese
- Adds savory flavor and helps the top brown in the oven.
- Flour
- Thickens the milk and egg mixture so it sets smoothly rather than watery.
- Butter
- Adds richness and fat that carries flavor and helps browning.
The step that matters
Pour the cream sauce over the macaroni and bake until light brown on top.. Eggs set when heated, so the custard firms as it bakes. Baking only until lightly browned avoids overcooking, which can make eggs curdle and the texture dry or grainy.
Swap the parsley
How well each one fits the dish's main ingredients (cheese, butter, milk, flour, egg, cream, sauce):
- Nutmegfits better
- Capersfits better
- Cinnamonfits about as well
- Parsleythe original
Fit is the average pairing score against cheese, butter, milk, flour, egg, cream, sauce. Candidates are from the same food group and used in at least 100 recipes.
