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 ↓
Cream Pie
Ingredients
Directions
Prepare
In a bowl, mix powdered sugar, flour, cream of tartar, and baking soda.
Beat the egg whites until stiff peaks form and set aside.
In another bowl, beat the egg yolks and add the grated lemon rind.
In a saucepan, heat the milk until scalding hot.
Make the filling
Stir in sugar, salt, and the beaten egg.
Cook over low heat, stirring until thickened.
Finish and assemble
Let cool.
Once cool, stir in vanilla extract.
Fold the egg whites into the cooled mixture gently.
Pour the filling between two pie crusts.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling as they cook, and whites are folded in for a light, airy texture.
- Flour
- Starch thickens the filling as it heats, giving it body and a set texture.
- Milk
- Forms the liquid base of the filling and adds moisture and richness.
- Sugar
- Adds sweetness and helps soften the set texture of the filling.
- Cream of tartar
- Acidifies the egg whites, helping them whip to stable, stiff peaks.
The step that matters
Cook the filling over low heat, stirring until thickened. Egg yolks can curdle or scramble if overheated. Low heat and constant stirring cook them gently while the starch thickens the custard evenly.
