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 ↓
New York Lemon Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Heat the milk in a double boiler.
Beat the egg yolks and add the sugar, mixing well.
Add the flour and mix until smooth.
Stir in the lemon juice and grated rind.
Pour this mixture into the hot milk and stir until thickened.
Remove from heat and gently fold in the beaten egg whites.
Top and bake
Beat the egg whites until stiff, adding 1 tablespoon of sugar for each white and a few drops of vanilla.
Pour the lemon filling into the baked pie crust and top with the meringue.
Brown the pie in a 350°F (175°C) oven for 10 to 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the base of the custard, giving it body and a creamy texture.
- Egg yolks
- Thicken the custard as they set with heat, giving it a smooth, rich texture.
- Egg whites
- Whipped into a foam that forms the light, airy meringue topping.
- Flour
- Helps thicken the custard so the filling holds its shape when sliced.
- Sugar
- Sweetens the filling and helps stabilize the whipped meringue.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
The step that matters
Stir the custard until thickened. The flour and egg yolks thicken only as the hot milk mixture heats; stopping early leaves a runny filling, while overheating can curdle the eggs.
