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
Make the custard
In a bowl, mix sugar, flour, egg yolks, milk, and salt.
Stir this mixture into a pint of boiling milk and cook until thickened.
Add vanilla for flavor and pour into a pre-baked pie crust.
Top and brown
In another bowl, beat the egg whites with sugar until stiff peaks form.
Spread the meringue on top of the pie and brown it in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk mixture so the custard sets into a firm, sliceable filling.
- Egg yolks
- Enrich the custard and help it thicken as it cooks, adding richness and a smooth texture.
- Milk
- Forms the liquid base of the custard that thickens when heated with the flour.
- Egg whites
- Whipped with sugar to form a stable meringue that puffs and browns on top.
- Sugar
- Sweetens the custard and, when whipped with egg whites, stabilises the meringue.
The step that matters
Cooking the custard until thickened. Flour starch must be cooked fully in the hot milk to swell and thicken; undercooked starch leaves the filling thin and runny once cooled.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, flour, egg, milk):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against sugar, flour, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
