Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and body to the filling while helping it thicken as it cooks.
- Chocolate
- Provides the main flavor and richness of the filling.
- Egg yolk
- Thickens the filling as it cooks and adds richness.
- Milk
- Adds moisture and loosens the chocolate into a smooth mixture.
The step that matters
Stir in the egg yolk and cook for 1 more minute. Egg yolk thickens when heated, but if it gets too hot or cooks too long it can curdle or scramble, leaving the filling grainy. Keep the heat gentle and stir constantly.
