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

What each ingredient does

Milk
Forms the liquid base of the custard filling.
Egg yolks
Thicken the filling and add richness as they set with heat.
Cornstarch
Thickens the milk mixture into a smooth, sliceable filling when boiled.
Grated chocolate or cocoa
Gives the filling its chocolate flavor and color.
Egg whites
Whipped into the meringue topping, giving it airy structure.

The step that matters

Add the cornstarch mixture to the boiling milk. Cornstarch only thickens fully when the mixture is boiling and stirred, so it must be added to hot liquid and kept moving to avoid lumps and a thin filling.
