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 and 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.
Cook the macaroni
Cook the macaroni in boiling water for about 1 hour until tender, adding more water if necessary.
Transfer the cooked macaroni to a pudding dish.
Assemble and bake
Pour the stewed tomatoes over the macaroni.
Add salt, butter, and sweet milk.
If the tomatoes are juicy, sprinkle flour for thickening.
Bake in a 350°F (175°C) oven until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the starchy base that softens and holds the body of the bake.
- Stewed tomatoes
- Provide acidity and moisture that flavour the pasta as it bakes.
- Sweet milk
- Adds moisture and richness, helping the pasta turn creamy in the oven.
- Flour
- Thickens the released tomato juices so the bake does not turn watery.
- Butter
- Adds fat for richness and a smoother mouthfeel.
The step that matters
Adding flour when the tomatoes are juicy. Flour thickens liquid only when it is evenly distributed and heated, so sprinkling it over juicy tomatoes lets it bind the released liquid instead of leaving the bake soupy.
Swap the tomato
How well each one fits the dish's main ingredients (butter, milk, flour):
- Potatofits better
- Arrowrootfits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
