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

What each ingredient does

Sugar
Provides sweetness and, as it dissolves and cools, helps form the fudge's fine-grained texture.
Butter
Adds fat for a smooth, rich mouthfeel and soft texture.
Milk
Supplies liquid that dissolves the sugar and gives the fudge its creamy body.
Baking chocolate
Provides the chocolate flavor and fat that contribute to the fudge's richness.

The step that matters

Beat the mixture until almost cold. Beating while the sugar syrup cools forms many tiny sugar crystals, which gives fudge its smooth, creamy texture. Beating too early or too late can leave it grainy or too stiff to pour.
