Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Maccaroni in Tomato Sauce
Ingredients
Directions
Cook the macaroni
Combine milk and water in a pot.
Bring to a simmer and add macaroni.
Cook slowly for 3 hours until tender.
Stir in grated cheese, salt, and cayenne, and mix well.
Assemble and finish
Transfer to a deep dish, layering with more cheese and tomato sauce.
If macaroni is dry, add small bits of butter and cayenne to taste.
Brown under a broiler or in a hot oven if desired.

Butter and sauce share little aroma chemistry, yet 15,338 recipes mention both: they likely 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 (in the method)
- Forms the body of the dish as it softens and absorbs the milk and water.
- Milk
- Adds richness and creaminess as it reduces around the pasta.
- Grated cheese
- Melts into the cooking liquid to add savoury flavour and a creamy texture.
- Butter
- Adds fat and richness, moistening the macaroni if it has dried out.
- Tomato sauce
- Adds acidity and savoury flavour between the layers.
The step that matters
Cook slowly for 3 hours. Long, gentle cooking lets the pasta absorb the liquid and soften without scorching on the bottom of the pot. Too high a heat can burn the milk and stick the macaroni, so the liquid needs to be watched and stirred.
