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

What each ingredient does

Baker's chocolate
Provides the chocolate flavour and, with the milk, forms the thick base of the frosting.
Sweet milk
Melts with the chocolate and thickens into a custard-like base that the sugar is added to.
Powdered sugar
Sweetens the frosting and stiffens it to a spreadable consistency.
Butter
Adds fat for a smoother, glossier texture and richer mouthfeel.

The step that matters

Stir the chocolate-milk mixture over hot water until it thickens. Gentle heat melts the chocolate evenly and lets the milk thicken into a custard without scorching or curdling. Overheating can seize the chocolate and leave it grainy.
