Vassar Fudges
Ingredients
Directions
Make the fudge
In a saucepan, combine sugar, milk, and chocolate.
Cook over medium heat until the mixture forms a soft ball when tested in cold water.
Stir until it thickens slightly, then pour into buttered tins.
Finish and cut
Once nearly cool, cut into small squares.

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 cooks, forms the firm sugar structure of the fudge.
- Milk
- Adds moisture and dissolves the sugar, giving the fudge a creamy texture.
- Chocolate
- Adds chocolate flavour and fat, contributing to the fudge's richness and smoothness.
The step that matters
Cook to the soft-ball stage. Sugar concentration determines the final texture. Cooking too little leaves the fudge soft and runny, while cooking too long makes it hard and grainy. Testing in cold water shows when the syrup has reached the right concentration.
