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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Assemble and bake
In a baking dish, layer the cooked macaroni, mutton, and tomato sauce, sprinkling each layer with salt and pepper.
Mix the cracker crumbs with the melted fat and cover the top with this mixture.
Bake until the crumbs are brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat that forms the main body of the dish.
- Cooked macaroni
- Adds starchy bulk that soaks up sauce and gives the casserole body.
- Tomato sauce
- Supplies moisture and acidity that keep the layers soft during baking.
- Cracker crumbs
- Form a crisp topping that browns in the oven.
- Melted fat
- Coats the crumbs so they brown evenly and stay crisp.
The step that matters
Cover the top evenly with the cracker crumb mixture. Crumbs coated with melted fat brown evenly and form a crisp crust. Thin or patchy coverage leaves bare spots that dry out or stay pale while the layers below can become soggy.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, mutton):
- Capsicumfits better
- Carrotfits better
- Tomatothe original
- Spinachfits about as well
Fit is the average pairing score against pepper, mutton. Candidates are from the same food group and used in at least 100 recipes.
