Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Unsalted butter
- Browned butter adds a nutty, toasted aroma and rich flavor to the filling.
- Brown sugar
- Sweetens the filling and, once melted and cooked, gives the pie its butterscotch flavor.
- Cornstarch
- Thickens the filling as it cooks, giving it a sliceable, custard-like body.
- Egg yolks
- Enrich and help set the filling, adding richness and body as it thickens.
- Milk
- Provides the liquid base of the custard and adds creaminess and softness.
The step that matters
Cook until thickened. Cornstarch needs to reach a full boil to reach its maximum thickening power, and the egg yolks must be heated enough to set without scrambling. Stir constantly so the starch does not scorch or clump at the bottom of the pan.
