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

What each ingredient does

Brown sugar
Adds moisture and a deep, caramel-like sweetness.
White sugar
Provides sweetness and the crystal structure that the fudge sets around.
Butter
Adds fat for a smooth, tender texture.
Chocolate
Gives the fudge its chocolate flavour and firmness as it cools.
Cream
Adds richness and moisture, keeping the fudge soft.

The step that matters

Stir until the mixture thickens. Stirring while the mixture cools and thickens encourages fine sugar crystals to form, giving a smooth texture rather than a grainy one. Stirring too early or too late changes the result.
