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

What each ingredient does

Eggs
Egg yolks thicken the custard, and whites lighten the set dessert.
Gelatin
Sets the milk mixture into a firm, sliceable dessert as it cools.
Milk
Forms the liquid base that the custard and gelatin set in.
Grated chocolate
Adds chocolate flavor and color to the custard base.
Sugar
Sweetens the custard and balances the bitterness of the chocolate.

The step that matters

Cook as for boiled custard, stirring constantly. Egg yolks thicken at around 160°F and can curdle or scramble if overheated or left unstirred. Constant stirring spreads heat evenly, keeping the custard smooth before the gelatin sets it.
