Chocolate Fudge

Ingredients

Directions

Make the syrup

  1. Combine sugar, chocolate, butter, milk, water, and salt in a saucepan.

  2. Stir until melted.

  3. Boil while stirring occasionally until the syrup forms a soft ball in cold water.

  4. Remove from heat and add vanilla.

Shape the fudge

  1. Let the pan cool until you can touch the bottom of the mixture.

  2. Beat the mixture until stiff and crumbly.

  3. Transfer to a board.

  4. Knead until smooth.

  5. Form into a long roll.

  6. Cut into pieces like oval caramels.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Granulated sugar
Dissolves into the liquid and forms the sugar structure that sets the fudge as it cools.
Baker's chocolate
Provides the chocolate flavor and fat that give the fudge its richness.
Butter
Adds fat for a smoother, richer texture in the finished fudge.
Milk
Adds moisture and milk solids that contribute to a creamy texture and flavor.

The step that matters

Let the pan cool before beating. Beating while the syrup is still hot makes large sugar crystals form, so the fudge turns grainy. Cooling until the pan bottom can be touched lets the syrup thicken so it sets smooth when beaten.
