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 ↓
Tomatoes Stuffed with Macaroni
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.
Prepare the macaroni
Break the macaroni into 1‑inch pieces.
Boil the macaroni in salted water for 30 minutes.
Drain the macaroni.
Cool the macaroni in cold water until needed.
Make the cheese sauce
Blend the butter and flour.
Add the milk and stir until smooth.
Season the sauce with salt and cayenne.
Stir in the grated cheese and cooked macaroni.
Stuff and bake
Stuff the mixture into the prepared tomatoes.
Sprinkle additional grated cheese on top.
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
- Provides the bulk and starchy body that holds the stuffing together.
- Butter
- Adds richness and fat that carries flavour into the sauce.
- Flour
- Thickens the milk into a smooth sauce that binds the filling.
- Milk
- Forms the liquid base of the sauce, giving creaminess once thickened.
- Grated cheese
- Adds savoury flavour and, when melted, a stretchy, binding richness.
The step that matters
Make the sauce smooth before adding the macaroni. Flour must be blended fully into the butter and milk added gradually while stirring, so starch hydrates evenly. Lumps stay unthickened and the sauce turns grainy instead of creamy and cohesive.

- Asparagusfits about as well
- Tomatothe original
Fit is the average pairing score against butter, flour, milk, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
