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 oven to 400°F (200°C).
Line a deep pie plate with pie crust, rolling thin and building edges with extra rows.
Trim edges neatly and bake until pale yellow.
Make the custard
Scald milk over boiling water.
Beat eggs together in a bowl.
Add sugar and flavoring to eggs and mix well.
When milk boils, pour gently over egg mixture, stirring until sugar dissolves.
For a lighter version, thicken the boiling milk with 1 tablespoon cornstarch blended with 2 tablespoons cold milk, then pour over 4 eggs and finish as above.
Bake and serve
Pour custard mixture into crust, ensuring about 1 inch deep.
If crust edge is not high enough, add another layer and notch neatly, wetting slightly to make it stick.
Bake until custard sets, about 15-20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate when baked, giving the custard its set structure.
- Milk
- Forms the liquid base of the custard, providing its creamy body and moisture.
- Sugar
- Adds sweetness and helps soften the custard's texture.
The step that matters
Pouring the hot milk into the eggs. Adding the boiling milk gently while stirring warms the eggs gradually. Pouring it in too fast can scramble the eggs and leave the custard lumpy instead of smooth.
