Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Provides sweetness and, when boiled, builds the firm structure of the fudge.
- Brown sugar
- Adds sweetness and moisture, along with a deeper, molasses-like flavour.
- Milk
- Supplies moisture and dissolves the sugars so the mixture can be boiled smoothly.
- Butter
- Adds fat for a smooth, tender texture and rich flavour.
- Chocolate
- Adds flavour and richness, and helps the fudge set smooth when stirred in off the heat.
The step that matters
Boil until a drop in cold water is firm. Sugar concentration determines the final texture. Boiling too little leaves the fudge soft and runny, while boiling too long makes it hard and grainy as sugar recrystallises.
