Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
A Lunch Dish
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.
Prepare
Preheat the oven to 400°F (200°C).
Assemble
Nearly fill a pudding dish with cooked macaroni.
Make a hole in the center and fill it with chopped cold roast mutton, seasoned to taste.
Cover with bread crumbs and bits of butter.
Pour rich tomato sauce over all.
Bake
Bake until brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 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
- Cooked macaroni
- Forms the bulk of the casserole and holds its shape as the dish sets.
- Chopped cold roast mutton
- Provides the savory meat filling that the macaroni surrounds.
- Bread crumbs
- Form a crisp, browned topping in the oven.
- Butter
- Adds fat that helps the bread crumbs brown and crisp.
- Rich tomato sauce
- Moistens the dish and adds acidity and savory depth as it bakes.
The step that matters
Bake until brown. The dish is done when the topping is golden, not just heated through. Browning comes from the Maillard reaction, which needs dry surface heat, so an oven that is not hot enough or a dish covered too long will leave the crumbs pale and soft.
Swap the tomato
How well each one fits the dish's main ingredients (mutton, bread, butter, sauce):
- Shallotfits about as well
- Tomatothe original
- Onionfits about as well
- Asparagusfits about as well
Fit is the average pairing score against mutton, bread, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
