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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
