Why it works: Vanilla and milk 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 ↓
Chocolate Chip Walnut Pie
Ingredients
Directions
Prepare
Preheat oven to 350 degrees.
Chill unbaked pie crust in freezer for 15 minutes before using.
Make the filling
Cream the butter with an electric mixer on medium speed.
Gradually beat in the sugars.
Add the eggs individually, beating well each time.
Beat in the vanilla.
Beat in the flour and salt until well blended.
Blend in the milk (don't worry if the filling looks a little lumpy at this point).
Stir in the chocolate chips and walnuts.
Bake and serve
Pour filling into the chilled shell, smoothing it out with a spoon.
Bake the pie on the center oven rack for about 50 minutes, turning it 180 degrees halfway through baking time.
When done, the top will be dark golden brown, and the filling will be set except for the center, which may slightly jiggle when you tap the pan.
Cool pie on a wire rack.
Serve warm, at room temperature, or chilled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the filling and set it into a custard-like texture as they bake.
- Unsalted butter
- Adds richness and tenderness, and creaming it traps air for a lighter filling.
- Light brown sugar
- Adds moisture and caramel-like flavor, and helps the top brown.
- Flour
- Gives the filling body so it holds together when sliced.
- Chocolate chips
- Melt during baking to give pockets of rich chocolate flavor and sweetness.
- Walnuts
- Add crunch and a toasty, slightly bitter note that balances the sweetness.
The step that matters
Judging when the pie is done. The center should still jiggle slightly when the pan is tapped. It sets fully as it cools, so overbaking can make the filling dry and firm rather than soft and gooey.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, egg, vanilla, flour, milk, chocolate):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against butter, sugar, egg, vanilla, flour, milk, chocolate. Candidates are from the same food group and used in at least 100 recipes.
