Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Potato Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Butter a shallow pie dish generously.
Line the edges with the pie crust.
Fill and bake
Fill the pie with mashed potatoes, seasoned with pepper, salt, and nutmeg.
Add marrow, small lumps of butter, chopped hard-boiled eggs, blanched almonds, sliced dates, sliced lemon, and candied peel on top.
Cover the dish with pastry.
Bake in a preheated oven at 400°F (200°C) for 30 minutes or longer, depending on the size of the pie.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

- Adds richness and fat, giving the filling a moist, savoury body.
- Hard-boiled eggs
- Add set, firm bits of protein that give the filling more substance.
- Butter
- Adds fat and richness, helping the filling taste rounded and moist.
- Blanched almonds
- Add crunch and a nutty flavour that contrasts with the soft filling.
