Why it works: Potato and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,052 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Irish Potato Pie
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.
Prepare the filling
Preheat the oven to 350°F (175°C).
Combine warm mashed potatoes, butter, sugar, nutmeg, and egg yolks in a bowl and beat until thoroughly mixed.
Pour the mixture into a lower pie crust.
Bake and top
Bake until set.
Beat the egg whites until stiff peaks form, then add 1 tablespoon of sugar and mix well.
Spread the egg white mixture over the pie.
Return to the oven for a few moments until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provides body and moisture, giving the filling a soft, sliceable texture.
- Butter
- Adds fat for richness and a smooth, tender texture in the filling.
- Sugar
- Sweetens the filling and helps the top brown lightly in the oven.
- Egg yolks
- Help the filling set into a firm, custard-like texture when baked.
- Egg whites
- Whipped into a meringue topping that traps air for lightness and browns in the oven.
The step that matters
Browning the egg white topping. Stiff peaks trap air for a light topping, but overbaking makes the meringue shrink and weep. Watch it closely during the short return to the oven.
Swap the potato
How well each one fits the dish's main ingredients (butter, sugar, nutmeg, egg):
