Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the milk mixture into a smooth, sliceable custard as it cooks.
- Egg yolks
- Enrich and thicken the filling, adding richness and body to the custard.
- Chocolate
- Provides the chocolate flavor and color of the filling.
- Milk
- Forms the liquid base of the custard and adds creaminess.
- Sugar
- Sweetens the filling and helps balance the chocolate's bitterness.
The step that matters
Cooking the filling over simmering water. Starch thickens only when the mixture reaches a full simmer and is stirred steadily, so stirring often prevents scorching on the bottom and lumps. Egg yolks must be cooked gently after they are added to thicken without curdling.
