Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sponge cake
- Provides the light, airy base that holds the layers together.
- Egg
- Thickens the chocolate mixture as it cooks and sets the filling.
- Milk
- Forms the liquid base of the filling and keeps it creamy.
- Chocolate
- Gives the filling its flavour and rich colour.
The step that matters
Cooking the filling until it thickens. The beaten egg can scramble if the heat is too high or the mixture is not stirred constantly. Stirring over medium heat lets the egg proteins thicken the milk evenly into a smooth filling.
