Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Casserole of 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.
Assemble
Line a plain mold with mashed potatoes, mixing in a little butter, the egg yolk, pepper, and salt.
Fill the mold with slices of underdone mutton.
Pour gravy over the mutton.
Bake and serve
Cover with more mashed potatoes and bake at 350°F (175°C) for 30 minutes.
Turn out and serve hot with additional gravy.

What each ingredient does
- Mashed potatoes
- Form the mold lining and top crust, giving a soft, moist body that holds its shape.
- Butter
- Adds richness and moisture to the potato layers.
- Egg yolk
- Binds the potato mixture so it holds together when turned out.
- Slices of underdone mutton
- Provides the main filling, which finishes cooking and becomes tender in the oven.
- Gravy
- Adds moisture and savory flavor to the mutton as it bakes.
