What each ingredient does

Gelatin
Sets the liquid into a firm, sliceable jelly as it cools.
Chocolate
Provides the main flavour and deep colour of the jelly.
Egg yolks
Thicken the custard as they cook and add richness.
Milk
Forms the liquid base of the custard, adding creaminess.
Sugar
Sweetens both the jelly and the custard.

The step that matters

Stirring the custard in the double boiler. Egg yolks can curdle or scramble if overheated, so cooking gently over simmering water while stirring constantly lets them thicken smoothly into a custard.
