Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Potato and Mutton Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove the mutton from the tin and discard the fat.
Boil the potatoes, then mash them with butter, milk, and seasoning.
Slice the onions and fry them in the fat from the mutton.
Assemble and bake
Butter a deep pie dish and line it with mashed potatoes.
Layer the sliced mutton mixed with onions on top, well seasoned.
Cover with a thick layer of mashed potatoes.
Sprinkle breadcrumbs on top and dot with small pieces of butter.
Bake in a 400°F (200°C) oven for 20 minutes.

What each ingredient does
- Potatoes
- Mashed potatoes form the soft base and top crust of the pie.
- Mutton
- Provides the savoury meat filling that forms the main body of the pie.
- Butter
- Adds richness and moisture to the mashed potatoes and browns the top.
- Onions
- Frying softens and sweetens them, adding flavour to the meat layer.
- Milk
- Makes the mashed potatoes smooth and moist.
