Why it works: Pepper and tomato 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 Lamb
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove skin and fat from the lamb slices and sprinkle with salt and pepper.
Cover the bottom of a baking dish with butter and cracker crumbs.
Layer and bake
Layer the lamb slices in the dish, then add a layer of boiled macaroni.
Add another layer of lamb and macaroni.
Pour tomato sauce over the top and cover with buttered cracker crumbs.
Bake in a 400°F (200°C) oven until the crumbs are brown.

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
- Cold roast lamb
- Forms the meat layers and provides the main savory flavor of the dish.
- Boiled macaroni
- Adds bulk and soft body between the layers of meat.
- Tomato sauce
- Moistens the layers so they do not dry out during baking, and adds acidity.
- Cracker crumbs
- Form a crisp, browned topping and soak up some moisture beneath it.
- Butter
- Adds richness and helps the crumbs brown in the oven.
The step that matters
Bake until the crumbs are brown. The topping needs enough heat to brown and crisp, but the dish must stay moist. Baking too long dries the lamb and macaroni, while stopping early leaves the crumbs pale and soggy.

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