Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Custard Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the crust
Preheat the oven to 400°F (200°C).
Line a deep pie plate with the pie crust, rolling it thin and building up the edges.
Trim the edges neatly and bake until pale yellow.
Make the custard
Scald the milk over boiling water.
In a bowl, beat the eggs together.
Add the sugar and flavoring to the eggs and mix well.
When the milk boils, pour it gently over the egg mixture, stirring until the sugar dissolves.
Pour the custard mixture into the crust, ensuring it is about 1 inch deep.
If the crust edge is not high enough, add another layer and notch it neatly, wetting it slightly to stick.
Bake
Bake until the custard sets, about 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a firm, sliceable structure as they cook.
- Milk
- Forms the liquid base that gives the custard its body and moisture.
- Sugar
- Adds sweetness and dissolves into the warm milk and eggs.
The step that matters
Pouring the hot milk into the eggs. Adding the boiling milk gently while stirring warms the eggs gradually. Pouring too fast can scramble the eggs, leaving lumps and a grainy custard instead of a smooth one.
