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 ↓
Yellow Macaroni and Cheese Baked with White Parsley Sauce
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Cook the macaroni
Boil water in a large pot.
Add coarse sea salt to the boiling water.
Add macaroni and cook for 20 minutes.
Drain the macaroni.
Place the drained macaroni in a 3-quart baking dish.
Make the custard and sauce
Mix in the chopped cheese and butter.
Beat the eggs, water, and thickening together.
Pour the beaten mixture over the macaroni.
In a separate pot, boil the milk.
Thicken the milk like a cream sauce.
Add the chopped parsley to the thickened milk.
Bake and serve
Pour the parsley sauce over the macaroni without mixing.
Bake in a 400°F (200°C) oven until the top is golden.

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, holding the sauce and custard.
- Eggs
- Set when baked, binding the custard layer and giving it a firmer texture.
- Cheese
- Melts into the dish, adding richness and savory flavor.
- Milk
- Forms the cream sauce base, adding moisture and a smooth, creamy texture.
- Thickening (flour or cornstarch)
- Thickens the liquid so the egg mixture and milk sauce become smooth rather than watery.
- Butter
- Adds fat and richness, helping the cheese blend smoothly and adding flavor.
The step that matters
Pour the parsley sauce over the macaroni without mixing.. Keeping the sauce as a separate layer lets the egg custard set beneath and the top brown during baking, rather than blending into a uniform, looser mixture.
Swap the parsley
How well each one fits the dish's main ingredients (cheese, butter, egg, flour, milk):
- Nutmegfits better
- Cinnamonfits better
- Capersfits about as well
- Parsleythe original
Fit is the average pairing score against cheese, butter, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
“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.
