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
Preheat the oven to 400°F (200°C).
Butter a shallow pie dish generously.
Line the edges of the dish with 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 another pie crust.
Bake the pie for 30 to 60 minutes, depending on the size.

- Hard-boiled eggs
- Set when heated, giving the filling body and structure.
- Butter
