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

What each ingredient does

Eggs
Thicken the custard as they set when stirred into hot milk, giving it body.
Milk
Forms the liquid base that the eggs thicken into a smooth custard.
Sugar
Sweetens the custard and balances the bitterness of the chocolate.
Chocolate
Provides the chocolate flavour and color of the custard.

The step that matters

Add 6 well-beaten eggs and stir for 3 minutes. Egg proteins set when heated, so the custard thickens gradually while stirred over heat. Stirring keeps the eggs from clumping or curdling into lumps, which would make the custard grainy.
