Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Pies
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).
Make the filling
In a bowl, combine the mashed potatoes, beaten eggs, milk, lemon juice, lemon rind, brandy, and butter. Mix until smooth to form a thin batter.
Prepare a pie crust and fill it with the potato mixture.
Bake
Bake until golden brown, about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provide the bulk and body of the filling.
- Eggs
- Set during baking to give the filling structure and richness.
- Butter
- Adds fat for richness and a smooth, tender texture.
- Lemon
- Adds acidity and aroma that brighten the sweet filling.
- Brandy
- Adds aroma and flavour to the filling.
The step that matters
Mix until smooth to form a thin batter. Lumps of potato or unevenly beaten egg stay visible after baking. Mixing until smooth gives the filling an even texture, and the eggs blend in better when beaten separately first.
Swap the lemon
How well each one fits the dish's main ingredients (potato, egg, milk, brandy, butter):

Fit is the average pairing score against potato, egg, milk, brandy, butter. Candidates are from the same food group and used in at least 100 recipes.
