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 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.
Make the filling
Cream the butter and sugar together.
Add the beaten egg yolks.
Mix in the potatoes and milk.
Fold in the beaten egg whites.
Fold in the lemon juice.
Bake and serve
Pour the mixture into pie shells or dishes lined with pastry.
Bake at 350°F (175°C) until set and lightly browned.
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk of the filling and a soft, starchy body once mixed.
- Eggs
- Set the custard as they cook and add richness and structure to the filling.
- Butter
- Adds richness and a tender texture to the filling.
- Sugar
- Adds sweetness and helps soften the texture of the filling.
- Milk
- Adds moisture and creaminess, loosening the potato into a smooth filling.
The step that matters
Fold in the beaten egg whites. Folding keeps the whites' trapped air in the filling, so the pie rises lightly. Stirring them in hard would deflate the foam and leave a denser pie.
Swap the mace
How well each one fits the dish's main ingredients (potato, milk, butter, sugar, egg, lemon, wine):
- Cinnamonfits better
- Nutmegfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against potato, milk, butter, sugar, egg, lemon, wine. Candidates are from the same food group and used in at least 100 recipes.
