Why it works: Milk and butter 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 ↓
Baked Macaroni with Tomato
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.
Make the sauce
Boil the macaroni according to package instructions.
In a saucepan, melt the butter over medium heat, then stir in the flour and cook for 1 minute.
Gradually add the milk, stirring constantly until the mixture thickens and boils.
Remove from heat and stir in the strained tomatoes, sugar, and pepper.
Bake and serve
Combine the sauce with the cooked macaroni.
Transfer to a baking dish and bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the structure of the dish, holding the sauce in its tubes and shape.
- Milk
- Provides liquid that, with the flour, thickens into a smooth white sauce.
- Flour
- Thickens the milk into a sauce when cooked briefly with melted butter.
- Butter
- Adds fat and richness, and forms the base of the roux with the flour.
- Strained cooked tomatoes
- Supplies the main tomato flavour and moisture to the sauce.
The step that matters
Thickening the milk into the sauce. Milk must be added gradually while stirring constantly, so the starch in the flour swells evenly and the sauce thickens without lumps. It must then come to a boil so the starch fully thickens.
Swap the tomato
How well each one fits the dish's main ingredients (milk, butter, flour, sugar, pepper):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against milk, butter, flour, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
