Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Scalloped Mutton
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 mutton
Remove fat and skin from the cold mutton and cut it into thin slices.
Layer and bake
In a buttered dish, layer the mutton slices and then a layer of cooked macaroni.
Season each layer with salt and pepper, and moisten with tomato sauce.
Repeat the layering until the dish is full.
Top with buttered crumbs and bake at 350°F (175°C) until golden.

Sauce and butter 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
- Cold roast mutton
- Forms the main body of the dish and provides its savory meaty flavor.
- Tomato sauce
- Adds moisture and acidity that keeps the layers from drying out during baking.
- Macaroni
- Adds bulk and a soft, starchy texture between the layers of meat.
- Butter
- Adds richness and helps the topping brown evenly in the oven.
The step that matters
Moistening each layer with tomato sauce. Cooked meat and pasta dry out quickly in the oven, so adding sauce to each layer keeps the interior moist and prevents a dry, crumbly result.

Fit is the average pairing score against mutton, sauce, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
