Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and a molasses-like flavour, and helps keep the fudge soft.
- White sugar
- Provides sweetness and forms the crystal structure that sets the fudge.
- Powdered chocolate
- Supplies the chocolate flavour and colour.
- Milk
- Supplies liquid and fat that give the fudge a smooth, creamy texture.
The step that matters
Let it cool completely before stirring. Stirring while the cooked sugar syrup is still hot lets large sugar crystals form, making the fudge grainy. Cooling first lets the mixture thicken into a smooth, fine-grained texture when beaten.
