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 ↓
Butter Scotch Pie
Ingredients
Directions
Make the filling
Combine brown sugar, water, and butter in a saucepan.
Cook until thickened, stirring to prevent burning.
Remove from heat and stir in egg yolks, flour, milk, and vanilla until smooth.
Pour the mixture into a pie crust.
Top and bake
Beat the egg whites until stiff, sweeten, and spread over the pie filling.
Brown the meringue slightly in a preheated oven.

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
- Brown sugar
- Provides the caramel-like sweetness and flavor that defines butterscotch.
- Egg yolks
- Thicken the custard filling as they set with heat, giving it body.
- Flour
- Thickens the filling and helps give it a smooth, sliceable structure.
- Milk
- Forms the liquid base of the custard and adds richness and moisture.
- Egg whites
- Whip into a stiff foam that forms the meringue topping, which browns in the oven.
The step that matters
Cook the filling until thickened, stirring constantly. Sugar and butter can scorch on the bottom of the pan if left unattended. Stirring spreads the heat evenly, and the starch in the flour must be cooked to thicken the filling fully.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, egg, butter, flour, milk):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against sugar, egg, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
