Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks enrich the filling and egg whites form a light topping once beaten.
- Cornstarch
- Cornstarch thickens the milk and chocolate mixture so it sets into a firm custard.
- Chocolate
- Chocolate gives the filling its main flavor and dark color.
- Milk
- Milk forms the liquid base that the chocolate and cornstarch thicken together.
- Sugar
- Sugar sweetens the filling and helps the egg white topping hold its beaten structure.
The step that matters
Add the cornstarch dissolved in 2 tablespoons milk and stir until thickened.. Cornstarch must be fully dissolved in cold milk before it goes in, then stirred while the mixture heats. Otherwise it clumps, and it only thickens properly once it reaches a simmer.
