Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Condensed milk
- Provides milk solids and sugar, giving the fudge its creamy, rich body.
- Brown sugar
- Adds sweetness and caramel notes, and its moisture helps set a soft texture.
- Butter
- Adds fat for a smooth, tender texture and a rich flavor.
The step that matters
Boiling to the hardness test. Fudge sets by crystallizing as sugar concentration rises during boiling. Too little boiling leaves it soft and runny; too much makes it grainy or hard. Testing by dropping a little into water shows when enough water has boiled off.
