Why it works: Butter and bread 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 ↓
Scalloped Mutton
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 the mutton
Chop the mutton coarsely and mix with salt and pepper.
Make the gravy
In a pan, heat the butter and stir in the flour until browned.
Add the water to the browned mixture and season with salt and pepper.
Assemble and bake
In a baking dish, layer the mutton and gravy, using three layers of gravy and two layers of mutton, finishing with gravy on top.
Sprinkle bread crumbs over the top and bake for 20 minutes at 400°F (200°C).
This dish can be prepared the day before and stored in a cool place.

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 body and savoury flavour of the dish.
- Flour
- Thickens the butter and water into a gravy, and browning adds a nutty flavour.
- Butter
- Carries the flour and adds richness to the gravy.
- Bread crumbs
- Form a crisp, browned topping during baking.
The step that matters
Browning the flour in the butter. Cooking the flour in fat until golden develops a nutty flavour and removes raw starch taste. Stir constantly so it does not scorch, then add the water before the gravy thickens unevenly.
