Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Yolks thicken the filling and set the custard, while whites whip into the meringue topping.
Corn-starch
Thickens the chocolate mixture as it heats, giving the filling body.
Baker's chocolate
Provides the chocolate flavour and rich body of the filling.
Milk
Carries the chocolate and forms the liquid base of the custard filling.

The step that matters

Cooking the chocolate filling until thickened. Corn-starch only thickens fully when the mixture reaches a boil and is cooked for a few minutes. Undercooked starch leaves a thin filling that will not hold its set once the tarts are baked and cooled.
