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

What each ingredient does

Sugar
Sweetens the mixture and helps form the thick, glossy body as it cooks down.
Milk
Provides liquid that dissolves the sugar and gives the ganache a creamy texture.
Chocolate
Supplies the main flavor and, once melted, sets into a rich, smooth mass as it cools.
Butter
Adds fat for a smooth, glossy texture and a richer mouthfeel.

The step that matters

Cooking to the drop test. Boiling until a drop holds its shape on a platter means the sugar has reached a concentration that will set firm as it cools. Stopping too early leaves the mixture runny, and cooking too long makes it grainy or hard.
